FREE Expert Solution

Recall that the quantum numbers that define an electron are:

Principal Quantum Number (n): possible values for n are 1 to ∞

Angular Momentum Quantum Number (l): possible values for l are 0 to n – 1

Magnetic Quantum Number (ml): possible values for ml are the range of –l to +l

Spin Quantum Number (ms): possible values for ms are either –1/2 (spin down) or +1/2 (spin up)
