The electrons present in the outer most shell are called valence electrons. The valency of an element is defined as its 'combining capacit..

Valency - It 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 has 4 valence electrons. K LC (6) 2 4 Carbon atom is capable of forming 4 bonds. Hence, its valency is fou..

Hydrogen generally shows + 1 valency like alkali metal..

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

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..
