Root Explanation

Heteroatom → It is formed from "hetero-" (from Greek "heteros", meaning different) and "atom" (from Greek "atomos", meaning indivisible). The word refers to an atom that is different from the main atoms in a molecule, indicating diversity in atomic composition.

Memory Tip

Think of 'different' ('hetero-') atoms that are 'indivisible' ('atom') in a molecule — that's what heteroatom means.
