What does “Homonuclear” and “Diatomic” mean? Organic Chemistry Hybridization and Atomic and Molecular Orbitals Drawing Atomic and Molecular Orbitals Diagrams for Molecules 1 Answer anor277 Mar 14, 2018 Well, #H_2# is a #"homonuclear, diatomic molecule...."# Explanation: It is #"homonuclear"# because the molecule is composed of atoms of the SAME kind....and it is diatomic because the molecule consists of TWO atoms.. Other #"homonuclear, diatomic molecules...."# include #Li_2#, #N_2#, #O_2#, #X_2#,,, #"Heteronuclear, diatomic molecules...."# include #HX#, #CO#, #ClF#, #NO#,,,,i.e. the diatom is composed of two different atoms....
