Hey there !

Valency is the combining capacity of an element whereas O.N. is the charge on an atom when combined with other atoms.

Valency is only a number and does not have +ve or -ve sign whereas ON is a charge and have +ve or -ve sign.

Valency can’t be zero whereas ON can be zero. e.g. C in CH2Cl2.Valency is always a whole number whereas ON may not be a number. e.g. Fe in Fe3O4 (8/3).

Valency of an element is fixed e.g. C = 4 always whereas O.N. may be different e.g. C in CH4 (-4) ; in C2H6 (-3) ; in CH3Cl (-2) ; in CCl4 (+4).

Hope it helps you !
