Options:

A) $ 5p<4f<6s<5d $

B) $ 5p<6s<4f<5d $

C) $ 4f<5p<5d<6s $

D) $ 5p<5d<4f<6s $

Show Answer

Answer:

Correct Answer: B

Solution:

According to Aufbau principle electron are filled in various atomic orbital in the increasing order of energy 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s.
