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.
Electrons shared during the formation of covalent bond, may be from one atom involved or each atom contributing equally to the bond formation.
An example of covalent compounds include, phosphorus (v) oxide, methane, water, CO2,etc.
