Question

For the formation of a covalent bond, both atoms should have ______ ionization energy.

Answer 1

Role of ionization energy in covalent bond formation:

1. The bonds are formed as a result of sharing of electrons between the atoms of the same element or different elements.
2. The energy required to remove an electron from the outermost shell of an atom is called Ionisation energy.
3. If an atom has low ionization energy then it is more likely that the atom will release electrons and form ions, which will lead to electrovalent bond formation.
4. For covalent bond formation, atoms need to have high ionization energy so that they do not form ions and electrons are available for sharing.

So, for the formation of a covalent bond, both atoms should have high ionization energy.
