‘n’ refers to the principle quantum number

‘l’ refers to the azimuthal quantum number

‘m’ refers to the magnetic quantum number

[a] when n = 1, L = 0 [Given] The orbital is 1s. [Can have maximum of 2 electrons]

[b] For n = 3 and L = 1 the orbital is 3p. [Can have maximum of 6 electrons].

[c] For n = 4 and L = 2 the orbital is 4d. [Can have maximum of 10 electrons]

[d] For n = 4 and L = 3, the orbital is 4f. [Can have maximum of 14 electrons]
