### 1/5 — This was bad…

*2023-06-24, version 3.1*

This game does not work ATTT ALLLLLL

### 5/5 — Brilliant

*2011-05-30, version 1.0.1*

It allows the user to become familiar with the structure of atoms by providing a sort of problem solving diagram of individual atoms, ions and isotopes.

It is a fantastic app that any lab teacher or professor would love to explain to his students.

To improve:
Nothing I can spot so far...

I would like to see however an app that has:
Balancing equations for elements
Yield equations for elements

Thank you for developing this!
