A)
B)
C)
D)
Correct Answer: C
Solution :
Key Idea Aufbau principle states that in the ground state of an atom, the orbital with lower energy is filled up first before the filling of the orbitals with a higher energy commences. Increasing order of energy of various orbitals is \[1s,\text{ }2s,\text{ }2p,\text{ }3s,\text{ }3p,\text{ }4s,\text{ }3d,\text{ }4p,\text{ }5s,...\text{ }etc.\] Therefore, is not obeyed by aufbau principle. Without fully filling of s subshell electrons cannot enter in p subshell in ground state of atom.You need to login to perform this action.
