Question

Explain the difference between oxidation state and valency of an element?

Answer 1

Hii Mate

Here Is Your Answer

1. Valency is the maximum no. of electrons which an atom can lose or gain while oxidation no. is the actual no. of electrons which the element lose or gain to form a molecule.

2. Valency is the property of an isolated atom while oxidation state is calculated for an atom is present in a molecule i.e, in a bonded state.

3. Valency of an element remains the same while its oxidation state may be different in different molecules.

Answer 2

Answer:

(i) Valency of the elements is usually equal to number of valency electrons (outer electrons) or equal to difference between 8 and number of valence electrons.

(ii) oxidation number or oxidation state of an element in a particular compound is the apparent charge acquired by its atom on the basis of electronegativity of other atoms in a molecule of a compound. It can be positive or negative (+,-) or zero.
