organic and atal gas chemical composition

Composition of the Atmosphere

Composition of the Atmosphere The gases in the atmosphere are composed of neutral, uncharged particles. Except for the noble gases, atoms in the gas phase share electrons with other atoms in chemical bonds so that their electron count can approach the more stable filled-shell configuration.

Organic And Inorganic Minerals

Because inorganic minerals and organic minerals have the same chemical compositions, they were confused by the early nutritionists. The mineral, iron, in the bloodstream has the same chemical composition as the mineral, iron, in a nail—iron is iron, after all. However, these nutritionists incorrectly reasoned that there were no
