5.8 Polar Covalent Bonds and Electronegativity Electrons in a covalent bond occupy the region between the bonded atoms. If the atoms are identical, as in H 2 and Cl 2, , electrons are attracted equally to both atoms and are shared equally. If the atoms are not identical, however, as in HCl, HCl, the bonding electrons may be attracted more strongly by one atom than by the other and may thus are shared unequally. Such bonds are known as polar covalent bonds. Prentice Hall © 2003 Chapter Five 24
