What is Covalency?How to find the covalency of any element
sarthak2luck:

Covalency of a element means how many maximum covalent bonds it can form.
The term Covalency is only for smaller elements which can form covalent because the larger elements show variable valency , so for them valency term is replaced by oxidation state or number.
i.e of period 1, 2 of p- block .
B,C,N the Covalency is 4 . Can be seen in compounds like BH4-, CH4, NH4+
For Oxygen Covalency is 3 in O3 .
For Fluorine Covalency is 1 . Etc.
Note : Covalency or valency is used only with period 1 &2 elements of p- block but after that elements can expand its Octet due to d- orbitals.
From third period onwards the term valency or Covalency is replaced by oxidation state or oxidation number.

Covalency is the property of atoms of different elements to form bonds with atoms of the same element or other elements.
Covalency of an element can be determined by knowing their electronic configuration.
for , example covalency of oxygen is 2 .
