Well, if we define a molecule as something that has more than one atom, the smallest molecules would be diatomic molecules (molecules with two atoms). The smallest diatomic molecule is hydrogen gas, H2, which consists of two protons and two electrons. Other common diatomic gases which have more electrons and more massive nuclei are O2 (oxygen), NO (nitrogen oxide), and CO (carbon monoxide).
