Complete Periodic Table ($0.99) by Rahul Aggarwal is an educational app that includes all 118 elements on the periodic table of elements. Never leave home without the knowledge of the universe with this handy and informative app.
Users can select any of the elements from the typical tabular display with elements listed by atomic number (the number of protons a particular element contains) with rows arranged so that elements with similar properties are in the same column. See, I just learned that by reading it in the History section of the app.
When you select one element from the table, you will see its atomic number and its chemical symbol. You will also see information regarding its chemical property, physical property, and discovery data.
The table shows a legend of the color representations so you know which grouping of elements you are looking at without having to look it up. For example, the nonmetals are all in blue and the halogens are all in green.
Additionally, the physical types of elements are designated by a different color of font. For example, the chemical symbol for liquids are in blue and gases are in red.
You can also view the elements as a list. In this format, the elements are listed by their atomic number. The name and chemical symbol of each element is also displayed. Just like with the table, when you select an element, you will see its basic information.
There is also a table of common polyatomic ions that are used in chemistry experiments. You can find ions listed by their the positive and negative charges, along with their chemical symbol and oxidation number.
In the Definition section, users will learn about the chemistry related definition of such words as alkali metals, halogens, and noble gases. In the History section, you will learn about the evolution of the periodic table from its official publication in 1869 by Dmitri Mendeleev.
There isn’t much to this app, other than the wealth of scientific knowledge you can always have with you. I’ve always been a fan of the periodic table. Now, I can read up on the elements at any time.
Because there isn’t anything in this app that you couldn’t find on the Internet, it almost seems silly to spend $0.99 on it. However, if you are sitting in chemistry class and can’t remember the chemical symbol for phosphate, this app could get you a better grade. All you have to do is pull it out of your pocket and pretend you are sending a text message. That is definitely worth a buck.
