Question

The energy of an electron in an atomic orbital of multi electron depends on which quantum number

Answer 1

Answer:

Two electrons into each orbital. Unlike in the hydrogen atom, the energy now depends both on n and ℓ.

Generally as the ℓ quantum number increases the energy is slightly higher. As a result 2s and 2p are no longer identical in energy in atoms with more than one electron

Answer 2

Explanation:

The higher the value of n, the more nodes there are in the electron wave. The higher the principal quantum number, the greater the energy of the electron. Therefore, the principal quantum number is determines the energy level of the electron. The azimuthal quantum number, ℓ, determines the shape of the electron wave.
