Oxygen Element Discovery, Its Properties And Evolution Of Atmospheric Oxygen

Oxygen element name means "acid forming" and derives from two Greek words: oxys (acid) and genes (form). The Earth was probably formed about 4,600 million years ago by the gravitational coalescence of cold material.

Initially there was a tenuous atmosphere of hydrogen and helium which was lost because of a weak gravitational field. The secondary atmosphere was created by the thermal and radioactive decay of various Earths constituents.
