The hydrogen molecule H2 does not contain any lone pairs. Each hydrogen atom has one electron, and when two hydrogen atoms bond to form H2, they share their electrons in a covalent bond. This sharing of electrons means that both hydrogen atoms achieve a stable configuration, resembling the nearest noble gas configuration, which in this case is helium.
Lone pairs refer to pairs of electrons that are not involved in bonding but are associated with a particular atom. Since in H2 all electrons are shared and there are no electrons left unshared on either hydrogen atom, we conclude that there are zero lone pairs in the hydrogen molecule.
