Answer:

In chemical bonds, atoms can either transfer or share their valence electrons. When electrons

are shared, the bond is called a covalent bond. When electrons are transferred, the bond is

called an ionic bond.

A covalent bond occurs when one or more pairs of valence electrons are shared by two nonmetallic atoms. The atoms that participate in covalent bonding share electrons in a way that

enables them to acquire a stable electronic configuration, or full valence shell. This means that

they acquire the electronic configuration of the noble gas of their row. Obviously, the name of this

rule is a misnomer. Helium, the noble (inert) gas of the first row, has only two electrons.

Hydrogen, the only element in the first row besides Helium, fulfills the octet rule by sharing two

electrons only.

In covalent bonds, the sharing of the electron pair may be equal or unequal. If sharing is unequal,

electrons spend more time around the more nonmetallic atom. These are called polar covalent

bonds. In such a bond, there is a charge separation with one atom being slightly positive and the

other slightly negative.

Thus, the covalent bond in an oxygen molecule, O2 (oxygen gas) is non-polar - electrons are

shared equally. The covalent bond in HCl (hydrogen chloride gas) is polar, with the H being

slightly positive and the Cl slightly negative.

An ionic bond occurs when one or more electrons from one metallic atom are transferred to

another non-metallic atom, resulting in positive and negative ions; these are termed cations and

anions respectively, which attract each other. When this happens, each individual ion achieves a

noble (inert) gas electron configuration. NOTE: All ionic compounds are termed salts, not just

table salt, NaCl.
