Question

what is Covalency?????​

Answer 1

Answer:

When an element shares electrons with other atoms of the same or different elements to acquire stable electronic configuration, it is called covalency. ... If it can share 2 electrons, its covalency is 2. Covalency of Fluorine – Fluorine has 7 valence electrons.

Answer 2

Covalency :-

Covalency is the number of electronpairs an atom can share with other atoms.

The total number of orbitals available in the valence shell is known as covalency, whether the orbitals are completely filled or empty .

For example :-

the electronic configuration of Boron (Atomic Number 5) is 1s. So, there are only two shells.
