Question

8. The energy of an electron in an atomic orbital of a
multielectron atom depends on
(1) The principal quantum number only
(2) The principal and Azimuthal quantum number
only
(3) The principal, Azimuthal and magnetic quantum
number only
(4) The principal, Azimuthal, magnetic and spin
quantum numbers
d-orbital with maximum electron density along two​

Answer 1

1 is the answer because principal quantum number is about size and energy of an eletron
