How many molecules are in one atom of oxygen?

Answer 1

Oxygen is, itself, an element of the Periodic Table. Therefore, there would only be one atom in a molecule of oxygen. However, at room temperature the gaseous atoms of oxygen are highly reactive with one another, as well as with atoms of other elements. Most oxygen atoms at room temperature will tend to bond together in groups of two, forming dioxygen (O2), the form of oxygen that we breathe.

Answer 2

There are two different types of Oxygen molecule O2 and O3 (also called Ozone). O2 has two atoms of Oxygen and O3 has 3 atoms of Oxygen.

Answer 3

1 atom of oxygen equals 1/2 molecule of oxygen, since the oxygen molecules in their standard state consists of two oxygen-atoms, O2.
