Question

Which of the following orbitals are not possible?
(a) lp
(b) 25
(c) 3f
(d) 4d​

Answer 1

Answer:

The first shell has only one sub-shell, i.e., 1s, which has only one orbital, i.e., 1s orbital. Therefore, 1p orbital is not possible. <br> (ii) The second sub-shell has two subshells, i.e., 2s and 2p. Therefore, 2s orbitals are possible. <br> (iii) The third subshell has three subshells, i.e., 3s, 3p and 3d. Therefore, 3f-orbitals are not possible <br> (iv) The fourth shell has four subshells has four subshells, i.e., 4s, 4p 4d and 4f. Therefore, 4d-orbitals are possible
