Question: The correct order of increasing energy of atomic orbitals is
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.
