what is valency ?

Valency describes how easily an atom or radical can combine with other chemical species. This is determined based on the number of electrons that would be added, lost or share if it reacts with other atoms.
    Valency is denoted using a positive or negative integer used to represent this binding capacity. For example, common valences of copper are 1 and 2.
