In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond. See Fig. 3-7.
Covalent bonds form when two nonmetals share an electron. Hi Covalent bonds occur when nonmetal elements have a unstable outermost shell know as the valence electrons. The two non-metal either give up of gain electrons and then live with the other element or elements outer shell. polar covalent bond is formed when 2 atoms are sharing the same electron unequally. It occurs because one of the atoms has a stronger affinity for electrons that the other. â¦. 24 people found this useful. 1  The Periodic Table of Elements Life is sustained by a number of chemical elements.
