Covalent compounds are compounds that are formed as a result of covalent bonding between nonmetal atoms.
Covalent compounds occur only between non metals, where atoms of the nonmetals involved join to form a covalent bond as a result of sharing of electrons.
<u><em>Electrons shared during the formation of covalent bond, may be from one atom involved or each atom contributing equally to the bond formation.</em></u>
An example of covalent compounds include, phosphorus (v) oxide, methane, water, CO2,etc.
