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 bo..

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 ..

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..

Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations. ..

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..

Variable Valency - Normally metals donate electrons from their valence shell so as to form positively charged ions such that the charge on the ion is equal to its electropositive valency. However, in transition elements, an atom loses electrons from the shell..

The chemical formula of a compound represents the composition of the molecule of the compound in terms of symbols of the elements present in ..
