The basic structure of the element silicon, symbol Si, an atom comprised of 14 protons, 14 neutrons, and 14 electrons.

In chemistry, silicon (LH:14), symbol Si, the 14th element (Z:14) of the periodic table, is an atom, with a mass of 28.09 amu, comprised of 14 protons, 14 neutrons, and 14 electrons; with an electron configuration of: [Ne] 3s2 3p2.

Overview

See main: Elemental composition of humans; Thims periodic table

The following is an early estimate of the percent silicon 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) [1]

Presently, it is known that in humans, sodium is the 15th most dominant element, by mass composition (0.001% mass), of the 26-elements in the standard human molecular formula.[2]
