Pretty much exactly what I wanted, but it would be nice if the atomic weight was included, it appears to say 18 for every element... would also be nice if you could shuffle the cards or pick categories to study, like first 18, metals, halogens, nobel gases, etc...other than that this is perfect.
Theres some polyatomic ions with the wrong charges (e.g. dichromate, phosphate, and carbonate) but the app itself is practical.
Wish it had more polyatomics
Some charges on the polyatomic ions are incorrect. I haven't looked at anything else
