Valency is the combining capacity of an element. It is the number of electrons in an atom that actually take part in bond formation. For example, carbon atom with an atomic number 6 has 4 valence electrons.K LC 6 2 4Carbon atom is capable of forming 4 bonds. Hence its valen..

Like halogens, hydrogen may also show 1 valency by accepting an electron. Example: NaH (Sodium hydrid..

A transition element and there-fore shows variable valency. It shows valency of +2 and forms divalent ions Fe 2 + (ferrous ions) and valency of +3 and forms trivalent ions Fe 3 + (ferric ions). The compounds of divalent ions are called ferrous compounds and trival..

Valency - Valency is the combining capacity of an atom. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. Depending on whether the atom loses, gains or shares electrons, the valency may be positive or neg..
