The chemical formula for oxygen is O2 and for individual oxygen  atom its symbol is O.   Gases such as oxygen exist as diatomic molecules.
  An oxygen molecule is diatomic ie. it has two atoms (O2). As the atomic mass of a single oxygen atom is indeed 16, the molecular mass of O2 is (2 x 16) = 32.xygen-17 has 9 neutrons and 8 protons. The only difference is the atomic mass due to the different number of neutrons. Number of p â¦ rotons & electrons stay the same. The difference is in the number of neutrons in the nucleus. Oxygen-15 has 7 neutrons, oxygen-16 has 8, and oxygen-17 has 9.
