this would make a great addition to all current elements and be able to select all states of matter for each element and by combineing elements you can create a new element EX: 2H+O=H2O.
maby it could start with a few basic elements like oxgen,hydrogen, and iorn. then set a goal to finish with all the elements like to finish the elements list for this by say version 55. then start adding more and more elements that can be made from combineing these. then set a goal to finish that.
