Question

write any two differences between the valence electrons and Covalency of an element

Answer 1

The valency and covalency are two terms that are related to the number of electrons present in an atom.

The main difference between valency and covalency is

valency is the number of electrons that an atom will lose or gain in order to stabilize itself

whereas covalency is the maximum number of covalent bonds that an atom can form using its empty orbitals.
