If the electronic configuration of an element is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 2 4s 2 , the four electrons involved in chemical bond formation will be_____.

Question

Philoid · Accepted Answer

The outermost orbital is also known as valence orbital and the electrons present in that orbital participate in the bond formation.

For the given electronic-configuration the d and s orbitals are the outermost orbitals.

Thus, the 4 electrons involved in chemical bond formation will be

3d², 4s².
