There are 118 elements on the periodic table, and each exists as a solid, liquid, or gas in its elemental state. (Well, some are difficult to tell because they decompose after a few milliseconds). Do you know which 11 exist as gases? If you do, you will win this game when you Slap Gas! Played just like Slap Jack, but uses a deck of 118 originally illustrated element cards. Each card contains the element symbol, atomic number, original illustration, and fun fact about the element's use in nature
