The basic animated[1] structure of oxygen, symbol O, an atom comprised of 8 protons, 8 neutrons, and 6 electrons.

In chemistry, oxygen (TR:277) (LH:14) (TL:291), symbol O, the 8th element of the periodic table, is an atom comprised of 8 protons, 8 neutrons, and 8 electrons.

Overview

See main: Elemental composition of humans; Thims periodic table

The following is an early estimate of the percent oxygen in humans:

“The human body contains carbon 13.5%, hydrogen 9.1%, oxygen 72%, nitrogen 2.5%, phosphorus 1.15%, sodium 0.1 %, calcium 1.3%, magnesium 0.001%, iron 0.01%, and traces of silicon and fluorine.”
— Carl Kelsey (1916), The Physical Basis of Society (pg. 7) [2]

Presently, it is known that in humans, oxygen is the 1st most dominant element, by mass composition (61% mass), of the 26-elements in the standard human molecular formula.[3]

Quotes

The following are quotes on oxygen:

“Why should a group of simple, stable compounds of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), 'struggle' for billions of years to organize themselves into a professor of chemistry? What's the motive?”
Robert Pirsig (1991), Lila: an Inquiry into Morals (pg. #) [4]
