Formal names for each letter

[Clarice Chui 2C]

Does anyone have an easy way to remember the full names for n, l, and ml?

[Brian J Cheng 1I]

n = principal number
l = orbital angular momentum number
ml = magnetic number

I would just try and hard-code it into my mind. I don't think the full names of the quantum numbers matter very much though--I'm sure the graders will know what you mean if you just use n, l, ml, and ms.

[305421980]

n = energy level
l = s, p, d, f classification
ml = axis each spins on

I remember them this way because its easier than the normal vocabulary.

[Michelle Song 1I]

To add on to previous responses, m_x is the spin of the electron and can be either positive or negative 1/2

[Eva Zhao 4I]

n = Principle Quantum Number
l = Angular Momentum Quantum Number
m_l = Magnetic Quantum Number
m_s = Spin Magnetic Quantum Number

n defines l and m_l and as such is the principle quantum number. For l, I tend to think of it as the odd one out; it's not the principle and it's not magnetic so it must be angular momentum. As for m_l and m_s, as mentioned previously, they are magnetic for the m's in their names. m_s has the s for spin.

[ThomasNguyen_Dis1H]

N is principal quantum number (shell), l is angular momentum quantum number (subshell), ml is the magnetic quantum number (orbital), and ms is the spin.
