    Hydrogen and Bonding. Having just one electron, hydrogen can bond to other atoms in one of two ways. The first option is to combine its electron with one from the atom of a nonmetallic element to make a covalent bond, in which the two electrons are shared. Hydrogen is unusual in this regard, because most atoms conform to the octet rule, ending up with eight valence electrons.

  • Why donpercent27t weTypes of Bonding. Atoms always try to have a full outer shell of electrons - in order to achieve this they will bond with other atoms. Because there is no ionic charge, covalent molecules are not as strongly attracted to each other as ionic molecules (covalent bonds are weaker).,In a hydrogen bond, the Lewis Base is the hydrogen bond acceptor (A) and the partially exposed proton is bound to the hydrogen bond donor (H-D).
