How many values of ml are allowed for an electron in a 5f subshell? ?

There are 7 values of ml are allowed for an electron in a 5f subshell namely: -3 -2, -1, 0, +1, +2, +3

In an atom, there are energy levels in the shell and subshell.This energy level is expressed in terms of electron configurations.

Writing the electron configuration starts from the lowest to the highest subshell's energy level. There are 4 sub-shells in an atom's shell, namely s, p, d, and f. The maximum number of electrons for each subshell is

Electron filling in subshells using the following sequence:

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

Each sub-shell also has orbitals drawn in the form of a square box in which there are electrons symbolized by half arrows.

Each orbital in an atom consists of 4 quantum numbers

Value of n: positive integer

value of l: s = 0, p = 1, d = 2, f = 3

ml value: between -l to + l

ms value: +1/2 or -1/2

Determination of electron configurations based on principles:

So for 5f orbitals, the value of a possible quantum number is

n = 5;

l = 3 (f = 3);

m = -3 -2, -1, 0, +1, +2, +3;

s = + - 1/2
