The formula of oxygen. Periodic table of elements - oxygen
WebOxygen is a chemical element with atomic number 8 which means there are 8 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Oxygen is the chemical element with the symbol O and atomic number 8.
