Question

The correct order of increasing energy of atomic orbitals is

• A. 5p < 4f < 6s < 5d
• B. 5p < 65 < 4p < 5d
• C. 4f < 5p < 5d < 6s
• D. 5p < 5d < 4f < 6s

Answer 1

Answer: (B)

The order in which the energies of the orbitals increases as follow
$1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s,5f,6d,7p,8s$
Hence, the correct order of increasing energy ' of orbitals is
$5d>4f>6s>5p$
