Oxygen. The partial pressure of oxygen (p A O 2) in the pulmonary alveoli is further used in determinations such as the alveolar-arterial (A-a) gradient of oxygen and in the right-to-left cardiac shunt. This happens because of the electron configurations in the oxygen, which become more stable and the bond between the O's is stronger when the oxygen is in diatomic form.

There are certain elements that in their gaseous form are diatomic, like O becomes O2. Industry Solution Oil & Gas (Downstream)> Industry Solution Oil & Gas (Downstream)> Formula & Average Pricing. At standard temperature and pressure, oxygen is a colorless, odorless gas with the molecular formula O2, in which the two oxygen atoms are chemically bonded to each other with a spin triplet electron configuration. 0.3305 Gal. Dioxygen or triplet oxygen can be defined using the molecular formula O 2 is the most familiar allotrope of Oxygen having two atoms per molecule. Oxygen gas is O2. There's one O on right side, 2 Os on left, so make coefficient 2 on right side to balance the oxygens. This bond has a bond order of two, and is often simplified in description as a double bond[7] or as a combination of one two-electron bond and two three-electron bonds.
