Info on the Oxygen Atom
There is a total of 2 energy levels on my oxygen atom model. It was discovered by Carl Wilhelm Scheele and Joseph Priestley. Priestley published his work first (in 1774) and gets most of the credit. Scheele discovered it in 1773 or possibly earlier. Oxygen is the third most abundant element in the universe, and necessary to sustain most life. Also, 2/3 of the human body is made of oxygen, due to it's presence in water.
