For a multielectron atom, which among the following orbital has maximum energy?a) 5fb) 3dc) 4sd) 2p​

Answers 1

Answer:

a) 5f

The orbital energies are compared with the help of n+l rule. The higher value of n+l, higher is the energy of the orbital.

5d=n+l=7

5f=n+l=8

6s=n+l=6

6p=n+l=7

The n+l value is greatest for 5f orbital.

Hence it has the highest energy among the given options.
