Great app with lots of info and no ads! But please get someone at Merck to go over the entries and correct where needed. It would be a good little project for a works student. Little errors and omissions include, for example: Tritium's isotopic abundance given as 10 - 16% and no radioactive half-life given, whereas for argon-39 it is. It would be nice to have the origin of an element's name in the description for all the elements including the transuranic ones.

Fantastic chemistry app that is easy to use, and has great useful information. Great for someone starting general chemistry or just wants to brush up on concepts.

Used to be my main periodic table app … until they added that nonscientific b.s. fake "element". Sorry, but I have VERY little tolerance for manipulation of core scientific information.
