My app is a periodic table app mixed with another app that quizzes you on the periodic table, the apps are called periodic table made by K12 and Periodic table of elements quiz. Say you need to study for a chemistry test, what you can do is go to the periodic table app and look at the properties of elements and then in combination with that you can go over to the quiz app and test what you’ve learned, the periodic table app is a little hard to read but over all it does work and everything is there after getting used to using the app, it however does not showcase ionic charges which limits its use so you might be better off with a printout of a periodic table, and the quiz app can only quiz you on period number atomic number symbols groups and category, so this limits its use so that you can’t go into orbitals and ions but for the right test it would still be very useful and I am actually considering using it myself, anyway so the periodic table app has all the groups periods atomic numbers and orbitals so basically everything that you need to know about an element minus ionic charges which isn’t hard to find anyway so I could honestly see myself using this app. Every time you click on a element it will bring up a card that has all the information that i’ve listed, they also have all the alkali metals, alkaline earth metals, non- metals, metalloids, and everything like that, however there is no way to make compounds to see how different elements react so it is a decent app but not the best. Onto the quiz app it has quiz modes that cover atomic symbols, atomic numbers, atomic mass, groups and periods and has each at a different level that gets progressively harder as you go on, so well this app is useful it definitely has it’s drawbacks. Overall I might use this study method but I think that I can do better work with a physical periodic table with me.
