I have written a periodic table application in LUA. Yes, I know that there already are a few periodic tables available, however none of them suited my needs. They were either too slow or didn't have enough data on the elements. As none of them made it possible for the user to add data, I finally made up my mind to write my own!

LUAtomic 0.5 -> download
I would really like this version to be helpful to many users which is why I will do my best to keep it up-to-date and add new functions as well as improve the speed.
If you have any thoughts, suggestions please let me know.
