For states with larger values of n that admit a d subshell, the d subshell is at even higher energy than the p subshell. in fact, its energy is higher than that of the s subshell for the n+1 state. with this in mind, which of the following are valid ground-state electron structures? 1. 1s2 2s2 2p63 s2 3p6 3d22. 1s2 2s2 2p6 3s2 3p6 3d113. 1s2 2s2 2p6 3s2 3p6 4s2 3d5a. 1b. 2c. 3d. 1 and 2e. 1 and 3f. 2 and 3

Explanation:

Correct order of energy of energy states within an atom is as follows

1s , 2 s, 2 p 3 s ,3 p, 4s , 3d,  4p, 4p,5s etc.

There is discrepancies in this order due to overlapping of outer orbitals with inner orbitals so sometimes outer orbitals have lower energy.
