Chloromethane (left) contains the heteroatom chlorine. The Grignard compound methyl magnesium chloride contains the heteroatoms magnesium and chlorine. The polarity is indicated by the letter δ.

Heteroatoms (from the Greek heteros , “the other (of two)”) are atoms in organic - chemical compounds that are not carbon or hydrogen . Often, but not exclusively, nitrogen , oxygen , sulfur or phosphorus atoms are part of an organic compound (such as cyclic compounds - heterocycles ). Because of the electronegativity difference between heteroatoms and carbon or hydrogen, the bonds between these atoms are mostly polar .
