Q.14.
Why is the 3rd energy able to fit more electrons?
Because 3 is a sacred number, just look at it!
Because the p-block that looks like it is part of the 3rd energy level is actually part of the 2nd energy level
Because the d-block that looks like it is part of the 4th energy level is actually part of the 3rd energy level
Because the third energy level has 7 s orbitals
