It increases on moving from left to right as more energy is released. The affinity of electrons – refers to the energy that is released when an electron is gained by an atom. On moving in a diagonal direction, atomic radius tends to increase. On moving from left to right, it increases, and on moving from top to bottom, it increases. Ionisation energy increases on moving horizontally across a period, whereas on moving in the downward direction, the ionisation energy decreases.Ītomic radii – the distance between the outermost electron and the nucleus is known as the atomic radius. Ionisation energy – this energy helps the atoms to remove the electrons. An exception in group 3 elements is present where electronegativity increases towards thallium. On moving in the downward direction, the electronegativity decreases. On moving from left to right horizontally in a periodic table, there is an increase in electronegativity. The Pauling scale is used to measure electronegativity. Some periodic trends and chemical reactivity in the periodic table are as follows –Įlectronegativity – measures the ability of a molecule to gain electrons within a chemical bond. The trends of the elements in a periodic table depend on various factors like electronegativity, ionisation energy, electron affinity, atomic radii, metallic character, and chemical reactivity. Periodic trends refer to the patterns of the properties of the chemical elements. The periodic trends and chemical reactivities of elements are shared below. The gas elements do not gain or lose their electrons because the electronic configuration is filled. Hence the elements on the left side in the downwards direction are the highly reactive elements. In a period, the chemical reactivity decreases on moving towards the right, whereas in a group, chemical reactivity increases on moving downwards. Hence the electronegativity and the ionisation energy determine a chemical reaction. The higher the reactivity of the element, the easier it is to combine. The electrons between the elements are shared, or the elements lose or gain the electrons. Therefore, as you go down the group the outermost electron becomes easier to lose and the reactivity increases as you go down the group.The rate at which a chemical substance or an element undergoes a chemical reaction is known as reactivity. Therefore, the attraction of the outer electron to the nucleus decreases as you go down group 1. This increases the shielding effect the positively charged nucleus has on the outer electron. The number of electron shells increases.The electrostatic attraction of the outer electron to the positive nucleus decreases as you go down group 1. Therefore, the outer electron is further away from the positive nucleus, as you go down the group. This is due to the number of shells increasing. Explaining the trend in reactivityĪs you go down the group the reactivity of the Group 1 increases because: So lithium would be the least reactive and francium would be the most reactive out of all the elements in group 1. This suggests that as you go down group 1, the reactivity of the elements increases. Looking at the reactions discussed beforehand, when going down group 1 the reactions get more and more vigorous. Trend in reactivity in a group can be explained using the electronic structure of atoms. Group 1: Reactivity (GCSE Chemistry) Group 1: Reactivity Group 1 – trend in reactivity

But no, the XU4 seems still to be kicking. Until now I was hesitating a little bit, because I thought that it would be just too old and will be kicked out by a more up-to-date hardware. Because it is somewhat mature and beats even the C4 in many areas. The C2 is a little bit newer but often tricky to get things running because of either the aarch64 or the video hardware (the reason why HK does not provide Kodi anymore for their latest Ubuntu).Ĭurrently I am about to buy a XU4. But it has become quite old and has reached EOL in many software terms. Until now I was more or less happy with my C1 for that.

It doesn’t take long, though, and it is very thorough. When you hit the “Scan” button, Sophos Home automatically launches a full scan of the system. Strangely enough, there aren’t any quick scans available. While this is very handy when the user doesn’t want the kids to “play around” with the software, for a regular user, this is rather inconvenient. If you want to configure the program, you’ll need to log into your account on the website. The main dashboard is minimalistic: it allows you to run scans, access the My Activity menu, and check the Settings. After installation, Sophos added over 1GB of files and as much as 17 processes in the background.ĭouble-click on the tray icon and the program’s friendly interface will come forward. The installation process only takes two-three minutes: all you need to do is follow the on-screen instructions. A name and an email address should be provided – this is a common practice among antivirus software. Sophos Free can be downloaded on the official website, but not before you create an account. Minimum requirements are 4GB of free space on the hard drive and 4GB of RAM. The Mac edition, in turn, is compatible with 10.11 up to 10.14. With a minimum of 1GB of hard drive space and 1GB of RAM, you’ll be able to launch it on your device. Scans also don’t take long to complete.Īs for the official system requirements, Sophos antivirus can work with Windows 7 up to Windows 10. During the check, we only saw a 7% drop in performance, and that landed Sophos the #2 spot on the list of the products with the least system impact. We used the OpenOffice benchmark test to see how this antivirus affects system performance. Ransomware protection is reliable, but it is only available with the paid edition. However, it’s one of the worst picks for phishing protection and, it is known to delete “innocent” files without warning the user about it. Next, we used the Wicar samples, and that’s where Sophos proved to be a good antivirus: it blocked every single malicious URL.įor desktop malware protection, Sophos Home is a decent solution. Out of the ten phishing URLs, it only blocked two (we tested Firefox, Chrome, and Microsoft’s Explorer, and the built-in protection proved to be better). Our team has put Sophos Antivirus through a phishing protection test. This means that in the case of a false positive, your legit files will be deleted without you even knowing about it. There was no warning (or a pop-up menu) offering a choice between putting those files in quarantine and deleting them. Once the files were downloaded, the antivirus deleted every single one (except for the compressed ones). It failed in the phishing, drive-by, compressed malware, and potentially dangerous apps tests. In the AMTSO test, Sophos Home only passed two of the six tests. AV-Comparatives and MRG Effitas tested Sophos Endpoint last year it’s an entirely different product, intended for business owners. This is a very impressive result, but, a lot has changed in the industry since then, and there’s no telling whether the antivirus will be equally effective this year. Sophos managed to score perfect 6/6 in all three tests, and got a total 18/18 score, entering the list of top ten antiviruses. They usually rank antivirus software in three categories: Protection, Performance, and Usability. In December 2017, AV-Test included Sophos Home into its big test. Back then, it managed to detect 98% of the malware threats, but that only landed it the 18 th spot (19 products were tested). AV-Comparatives haven’t adequately tested this product since 2016. And, we ran our own series of tests to see how Sophos Antivirus performs in the real world. Sadly, with Sophos there aren’t many recent lab test results available, except for the ones conducted by AV-Test. In this Sophos antivirus review, we’ll go over both the free and the paid editions and talk about all the pros and cons. Furthermore, Sophos supports multiple platforms (including Win, Mac, iOS, and Android) and features a parental control suit. First of all, it is relatively affordable secondly, it can protect up to ten devices simultaneously. The Premium package offers an excellent deal for a big family. But our hands-on testing proves its efficiency. Sadly, there aren’t many third-party lab tests available at this moment. It might not provide the best protection against phishing, but it does prevail in malware protection. If you’re looking for a decent antivirus to protect your OS, Sophos Free will be a good pick. Sophos has always been one of the most prominent players in the industry thanks to its best antivirus and security suite solutions. The pickup senses the electrical pulses generated by the spark plug firing and sends the signal to the timing light, allowing it to determine the precise timing of the ignition.
That combination of options makes a pretty strong case for going with Lowrance when it comes to mapping lakes that have poor coverage, especially in Canada. You can also now use Navionics SonarCharts live, which is the equivalent of Humminbird Autochart or Garmin Quickdraw with any Lowrance HDS Gen 3, Carbon, or Elite TI. It can take several days for your uploaded sonar data to be incorporated into the Social map layer. The maps created from your own sonar data will be ready for download in about 2-6 hrs on average I'd say, but if it's a large file, a merge of several files, or they're very busy with uploads, it has taken up to 24 hrs. The power of all the Insight Genesis uploading their data to the Social Map is a HUGE advantage when it comes to getting quality map data on Canadian lakes, and the best part is, it's free. The existing Social Maps will get you started and they get better and better all the time. Lowrance gives you the advantage of Insight Genesis AND Navionics SonarCharts Live. How long after uploading data are the maps available for downloading?Īny comments or suggestions would be appreciated. Joesph available and a lot of maps for my home lake of Whitefish, so that appears to be a plus for me. There are already some maps for part of Lake St. Lowrance Insight Genesis: Maps are shared via GoFree. Can it be shared? Is there a community to access for other maps? It looks like a Windows PC is required to utilize the program, which is an issue for me since I use a Mac. Map updates are very large, and this process may take a long time on slower internet connections. The Garmin Express application downloads and installs the updates onto your device. To install a specific update, click View Details, and click Install next to the update you want. The Humminbird site makes a point of keeping the data private. Select an option: To install all available updates, click Install All. Humminbird Autochart Live: Looks like immediate mapping with up to 8 hours on the unit. Could we share data via cards or would the data need to be uploaded to the community sharing? I'd like to share it with everyone but would like to immediately have access to our shared files. Joseph on the Quickdraw community website, but a member of our group just got a Garmin unit, so 2 of us would be mapping. Currently, there are no maps available to share for Lake St. To share, the data is uploaded via a computer and the map is available within a day. Garmin Quickdraw: My understanding is that maps are drawn directly on the unit instantly and up to 75 hours of data can be saved on a 2GB card. What I'm looking for are comments about my assumptions or recommendation from users. It appears that my choices are: Garmin Quickdraw, Humminbird Autochart Live, and Lowrance Insight Genesis. Together, perhaps, we could generate some useable maps. Ideally the maps I make could be shared with others that fish the lake. I'll never be there long enough to map the entire lake but would like to map the areas I already fish. I plan to get a new gps/sonar unit and would like to map part of the lake. The Ontario lake I fish has no electronic maps available that have depths. A watermark subtly displays, no matter where your photo goes, that it’s yours.

When the two outliers are removed, Sandra can see that most of the data is grouped closely together. She recalculates her statistical measures and creates a new box-and-whisker plot: Sandra believes that neither Teresa nor Lisa’s scores are useful in gauging her speed. Another teammate, Lisa, had fallen during the race but got up and continued to the finish line. She knows that her friend, Teresa, is fast with a time of 10.1. When Sandra analyzes the box-and-whisker plot, she finds that her time, 11.1 seconds, is barely less than the first quartile. She finally draws whiskers from the quartiles to the extremes. She places the extremes, 10.1 and 19.6, on the numbers with points. Then, she draws boxes between the quartiles and the median. Then, she finds the first and third quartiles and places these numbers on the number line. The 10 th and 11 th data values are both 11.6. Then, she finds the median and places this number on the number line. The extreme maximum is 19.6 and the extreme minimum is 10.1. Next, she draws a number line that includes the extremes. Sandra’s time was 11.1 and she wants to know how she compares to the rest of her team. They recently ran a 100 meter dash at a track meet and recorded official times. Take a look at how removing an outlier can affect the interpretation of the data. Sometimes when you consider data, you might choose to remove the outliers in order to draw better conclusions based on the data. When you discuss measures of central tendency like mean, median, and mode, you must also remember that in the real world there are many exceptions. Outliers are points that are unusually large or small compared to the rest of the data. Finally, the extreme minimum, 35, appears to be an outlier as the left whisker is very long compared to the rest of the plot. The extremes in this data set are approximately 35 and 129.Ĭ. The first quartile is approximately 82 and the third quartile approximately 104.ĭ. The interquartile range, then, is 104 – 82 or 22.Į. Use the given box-and-whisker plot to identify: a) the extremes, b) the median, c) the quartiles, d) the interquartile range, and e) the outliers (if any).Ī. If there isn’t a single point that is exceptionally far from other points, then an outlier doesn’t exist. It can be calculated by subtracting the first quartile from the third quartile.įinally, the outliers, data items that are far away from the general trend, can be located as extremes that cause the whiskers to be exceptionally long. This shows where the middle half of the data is located. The interquartile range is the range between the first quartile and the third quartile. The second and fourth points, between the median and the extremes, give the quartiles. The third or middle point gives the median of all the data. The first and last points give the extremes of the data. Boxes are then drawn between the quartiles and whiskers are drawn to the extremes.Ī box-and-whisker plot that is already constructed can quickly supply statistical measures by looking at the five points. Finally, use the smallest data value and the largest data value as the endpoints or extremes. The median of each half, the quartile, is then calculated. Use the median as the middle point on the box-and-whisker plot and to split the data in half. Then, create a number line that shows the range of the data using equal intervals. The smallest data point (the extreme minimum) and the largest data point (the extreme maximum) are also displayed on the graph.įirst, arrange the data in order from smallest to largest. The data are divided into four equal parts, separated by points called quartiles. A box-and-whisker plot is created by determining five points. Box-and-whisker plots display the distribution of data items along a number line. \)Īt times it is useful to get a general idea of how data clusters together. |
