Question

Among 3s,3p,4s 3d which atomic orbital has highest energy

Answer 1

Answer:

Explanation:

the 3s electrons experience the least shielding, and the 3d electrons the most. ... The energy of an electron depends on the effective nuclear charge, Zeff. Because Zeff is larger for the 3s electrons, they have a lower energy (are more stable) than the 3p, which, in turn, are lower in energy than the 3d.

Answer 2

Explanation:

The energy of an electron depends on the effective nuclear charge, Zeff. Because Zeff is larger for the 3s electrons, they have a lower energy (are more stable) than the 3p, which, in turn, are lower in energy than the 3d.

Why do 3s,3p, and 3D orbitals have the same energy in a hydrogen atom, but have slightly different energies in multi-electron atoms? ... The degeneracy of the orbitals is caused by conservation of angular momentum.
