valency is the combining capacity of an element
valency can be found using the valence electrons
metals have tendency to lose electrons to achieve octet
eg :- sodium so electronic configuration is 2,8,1
sodium can lose 1 electron therfore valency of sodium is 1
non-metal have a tendency to gain electrons
eg:- for example chlorine electronic configuration is 2,8,7 it can gain 1 electron to achieve octet therefore it's valency is 1
