how to get valence no.

The members of group VA generally show trivalent character but nitrogen shows more than one valency ranging from +1 to +5. Example: Oxide of Nitrogen N 2 O NO N 2 O 3 NO 2 N 2 O 5 Name Nitrous Oxide Nitric Oxide Nitrogen Trioxide Nitro..

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..

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 negative or..

Metals have 1 to 3 electrons in the outermost shell of their atom..

. They behave as a single unit and the valency of radicals is the overall net charge of the group. The radicals maintain their identity in the chemical changes but are incapable of independent existence. Remember : Radicals Formulae Hydroxide - OH - Sulphate - SO 4 - Nitrate - NO..

The outermost shell of an atom is called its Valence shell. It is the decisive shell during a chemical reaction. The electrons of only this outermost shell are involved during chemical combinations; electrons are either given out from the outermost shell, or accepted into the outermost s..
