What is molecule: Amoleculemay be homonuclear

Amoleculemay be homonuclear, that is, it consists of atoms of onechemicalelement, e.g. two atoms in the oxygenmolecule(O 2); or it may be heteronuclear, achemicalcompound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H 2 O).
