Diatomic molecules are molecules composed only of two atom s, of either the same or different chemical element s. The prefix di-means two in Greek. Common diatomic molecules are hydrogen (H 2), nitrogen (N 2), oxygen (O 2), and carbon monoxide (CO).he bond in a homonuclear diatomic molecule is non-polar and covalent.
