The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.Ok so I'll take you through some interesting facts and data about Oxygen (That most people don't know).
Oxygen Overview
Atomic Symbol
O (Oxygen)
Description
Colorless, odorless, tasteless gas; pale blue liquid. Third most abundant element in the universe. It is the most abundant element in the earth's crust, and makes up almost 21% of the atmosphere.
State at 20 °C
Gas
Sources
Obtained primarily from liquid air by fractional distillation. Small amounts are made in the laboratory by electrolysis of water or heating potassium chlorate (KClO3) with manganese dioxide (MnO2) catalyst.

Uses
Used in steel making, welding, and supporting life. Naturally occuring ozone (O3) in the upper atmosphere shields the earth from ultraviolet radiation.
