How can we determine the valency of transition elements

Expert Answer:

Valency can be determined by electronic configuration.
Electronic cponfiguration of transition elements is ns2 (n-1)d.  Electrons present in ns2 are valence electrons. 
Most common valency is 2. Transition metals have 2 valence electrons It is very general statement about valency. But they have variable valency so all valencies are not predictible. It depends upon their chemical reaction.
