But depending on the composition of the substance, the bond
between atoms in a compound is classified as either
covalent, ionic or metallic.
–The
chemical bond in compounds made up only of non-metals is referred to
as covalent bond.
–The bonding in compounds made up of a metal and a
non-metal (or polyatomic ion) is referred to as ionic bond.
–The
third and last kind of chemical bond is metallic
bond, which is the chemical bond found in
metals, as the name suggests.
We will consider each of these bonds in turn, starting with
covalent bond, and look at how bonding determines the structure as
well as the properties of a substance.
