Finally got down to doing some concept art for my element (and compound) mascots while trying to get used to my tablet again!
Anyway, they are Hydrogen, Carbon, Oxygen, Potassium, Water, Polychlorinated Dibenzo Dioxin, and Polychlorinated Dibenzo Furan. Bohr Rutherford diagrams and water molecule image from the Wiki entry of each respective compound/element.
Wow okay this is cute
