In a multi-electron atom, the energy of a 2p-orbital is:

JEE Main Chemistry question

In a multi-electron atom, the energy of a -orbital is:

(A)Less than that of the -orbital
(B)More than that of the -orbitalCorrect
(C)Equal to that of the -orbital
(D)Double that of the -orbital

Answer: (B)

Solution

In a multi-electron atom, orbital energies depend on both and (unlike in hydrogen, where only matters), because the orbital has a greater probability density close to the nucleus
