Question

diffrence between oxidation number and valency by giving examples


please in points ​

Answer 1

Explanation:

All compounds are made of atoms of different elements. These atoms are combined in different ratios according to the number of available free orbitals they have or the number of electrons that a particular atom can release. Valency and oxidation state are two terms used to explain the reasons for these different combinations of atoms. The main difference between valency and oxidation state is that valency is the number of electrons present in the outermost shell of an atom of a particular element whereas oxidation state is the number of electrons that an element in a particular compound has lost or gained.

Answer 2

Answer:

Valency refers to the number of bonds formed by an atom in a molecule. Oxidation number is harder to define. ... Oxidation number and valence are sometimes equal. For example in NCl3, N forms three bonds (valency = 3) to the more electronegative Cl (giving N an oxidation number of +3).
