Define valency​

Answer 1

Answer:

Valency is defined as combining capacity of an atom. It is determined by the number of valence elctrons present in an atom.

Answer 2

Answer:

Valency is the combining capacity of an element. For metals, it is equal to the number of electrons in the outermost shell of their atoms, and for nonmetals it is eight minus the number of electrons in the outermost shell.

Transition metals like iron and copper show more than one valency in compound formation.
