![]() ![]() Over the past four seasons, Allen has recorded 2,325 rushing yards and 31 touchdowns on the ground. And in reality, Allen checks the box on the mobility aspect in a way that puts him not far behind a player like Jackson. There’s no question that Allen fits the modern era of the NFL well, which values some level of mobility, even though a quarterback doesn’t have to match the same level of running style as someone like a Lamar Jackson to succeed. Those 42 total touchdowns also made Allen the quarterback with one of the highest numbers in that category, second only to Buccaneers quarterback Tom Brady, who had 45 total touchdowns in 2021. He made several statements in 2021, becoming one of just six quarterbacks in the history of the league to exceed 5,000 yards and 42 touchdowns within a single season. One of the prime examples of that was the 9-6 loss to the Jacksonville Jaguars in November where Allen struggled, completing 31-of-47 passes for 264 yards with two interceptions. What this comes down to for Allen is maintaining a high level of consistency, not taking a step back statistically and avoiding some of the valleys that showed themselves last season. Josh Allen stats (2020-21): 66% completion, 8,951 passing yards, 1,184 rushing yards, 87 total TD, 25 INT, 99.2 QB rating.Josh Allen stats (2018-19): 56% completion, 5,163 passing yards, 1,141 rushing yards, 47 total TD, 21 INT, 78.2 QB rating.The following season, he held a 63.3% completion rate, throwing for 4,407 yards with 36 touchdowns and 15 interceptions. He completed 69.2% of his passes for 4,544 yards with 37 touchdowns and 10 interceptions in 2020. Allen finished that year completing 58.8% of his passes for 3,089 yards with 20 touchdowns and nine interceptions.Īllen made a promising jump in the next two seasons, but that’s where things get a little bit wacky. Though, the numbers and film reflected there was still plenty of work to do. The 2019 season saw him take a step in completion rate and touchdown-to-interception ratio. ![]() In his rookie season of 2018, Allen completed 52.8% of his passes for 2,074 yards with 10 touchdowns and 12 interceptions. ![]() You'll never have to pay for another Sudoku book again.

WordPress was always just thought of as a blogging platform, but it has evolved in to much more than that and you can now create stunning looking websites with blogs - there are a good range of free templates to choose from and if you want your blog on the front page of your site you can have this, or you can change it to another part of your site if you want a static front page. Joomla is good also and you can have a Blog with it too and there are lots of themes to choose from, but sometimes you have to pay for extras with Joomla - you can download Extensions and Plugins, but they may not always be free. There is a Blog module that you can enable and that comes in Drupal Core with no need to download an extra module. You can allow people to complete forms on the site itself and the results to be sent to you. You can have a membership site if you want it and this is easy to do - people can sign up for an account and you can restrict their access to certain parts of the site and then limit what they can do. There are a lot more themes that you can use and if you want increased functionality in Drupal, then you can download Modules and install them. Drupal has a reputation for being quite hard and Drupal 6 was, but with the advent of Drupal 7, things got a lot easier. I have used all of them in the past, but most recently Joomla and Drupal. There is probably no best one, but you need to look at them all and use the one that best fits your needs. The top CMS's that most have heard about and use are Drupal, Joomla and WordPress. I have used HostExcellence in the past and they support all the CMS's including WordPress, so you should have no problems there. GoDaddy hosting is good for this or you could do a search for WordPress specialist hosting, but in the end you don't need MAMP at all - this is only for local use and not hosting. If doing it manually is too much, then find a host that offers one click install for the CMS's - this way it will install it on your hosting account and set up the database for you and you just choose the password and usernames and it is done. You then need to go and set up the database at your host, normally done via PhP MyAdmin and once this is done, you connect the 2 together and you are up and running and you can start creating your site. Then download the latest copy of WordPress from and upload the contents of this folder to your main hosting account, so that it is directly on your domain name. If they don't then you can easily install it manually on your hosting account - you would need to download firstly an ftp programme such as Cyberduck or Transmit, so that you can connect with your hosting. You only need MAMP if you are proposing to use WordPress locally on your Mac.ĭo you have hosting and a domain name? If you do, then go to your host and lots now offer one click install for the CMS's - which are WordPress, Drupal and Joomla. If you want to combine both with a website and a blog, then yes, would be the way to go, but you DON'T need MAMP for this. That is the problem with Blogger, that you won't get your own domain name.ĮverWeb does not have a blog feature yet - that is to come, but if you watch the support videos there are workarounds for this. There are other alternatives such as RapidWeaver, Sandvox, Freeway Pro/Express, WebAcappellla 4, Flux 4 and others, so take a look at what suits you best and you can download free trials of all of these. The best alternative to iWeb is probably EverWeb at the moment - go and take a look at. It is not hard to use - just download it and install it and then download a full copy of the current and up-to-date WordPress from and place it in the htdocs folder and then go and set up your database at PHP My Admin and call it Wordpress and then it is the standard passwords and then just open locally and select WordPress and then link the database to WordPress and you are aware - however, as I said WordPress is meant to be used on a server and not locally on your Mac. You can use it locally on your Mac if you want to, but you need to download something called MAMP from the internet that lets you run My SqL, Apache and PHP locally on your Mac. No, WordPress was never intended to be used locally on a Mac really and with WordPress all you do is purchase your domain name and hosting account and load WordPress with a one click install if your host offers it. ![]() They are found in very minute quantities naturally. These rare earth elements are divided into lanthanides (elements 58 – 71) and actinides (elements 90 – 103). The inner transition or f-block elements are placed under the transition ones in a separate table. The groups 3A, 4A, 5A, 6A and 7A consist of p-block elements. They have similar chemical properties like production of colored compounds and variable valency. The groups are present in the following order: 3B, 4B, 5B, 6B, 7B, 8B, 1B, and 2B contain transition metals or the d-block elements. They contain the same number of outer electrons, and thus show similar chemical properties. Both 1A and 2A contain the s-block elements. The alkali earth metals are found in group one, whereas the second group contains alkaline earth metals. The vertical rows are known as groups and the horizontal rows are known as periods. Thus, the elements are arranged in the order of increasing atomic number (Z) left to right across the table. With this knowledge, he was able to predict the presence of new elements. With these breakthroughs, Mendeleev could not move further as the Rutherford-Bohr model of the atom was yet to be discovered.Īfter about four decades, Henry Moseley in 1913 showed the atomic number (charge) and not the atomic weight, as proposed by Mendeleev, as the fundamental chemical property of any element. It was Mendeleev, who predicted undiscovered elements like eka-silicon (as he found a gap between silicon and tin), today known as germanium, gallium, today called aluminum, and eka-boron, known as scandium. He got a table with gaps and spaces, which meant that there were further elements yet to be discovered. The ones with similar properties were kept in the same column.He positioned element with higher atomic weights on the left side.He arranged the elements in his table on the basis of the following points: Mendeleev found out that 65 elements that were known in his time, could be arranged in a grid. There were many versions introduced before Mendeleev’s table, but he was the one who illustrated the recurring periodic trends in the elemental properties. They follow a pattern, i.e., in an increasing order of the atomic number.ĭmitri Mendeleev, a Russian chemist, is credited as the first person to invent the periodic table in 1869. These elements are arranged in rows and columns – left to right and top to bottom. The elements arranged in the periodic table are great help to scientists, chemists, scholars, researchers, and even students in understanding their various properties and characteristics at a glance. We cover the history of the periodic table thoroughly in our blog post.The periodic table is one of the most important points of reference in the branch of chemistry, and is often known as the Bible of chemical sciences. The Periodic Table has constantly been improved and developed over the past 200 years, but in 1869 Dimitri Mendeleev finished the first version of the periodic table as we know it today, by arranging the elements by atomic mass and leaving spaces open for the elements that were not yet discovered. The periodic table also gives us an idea of what the characteristics of an element might be and help us predict how an element might react based on in which group it is located. The Periodic Table of Elements can be used as assistance in chemical calculations, when a specification of an element is needed it is easily found in the Periodic Table. The table lists all the elements that are currently known (118), in descending order of the number of protons that are present, in a single atom of the element. The Periodic table of elements is a tool, developed by scientists over hundreds of years. List of all the elements and the elemental properties: |
