what is valency?

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

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..

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 fo..

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 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 neutral res..

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

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..

The number of valence electrons is the valency of the element. The valency of an element can also be calculated by finding the number of electrons required to complete octet (8)i.e., 8 - Number of valence electrons = Valency..
