Match the entries in column I with the correctly related quantum number(s) in column II.

Explanation

`A rarrQ, BrarrP, Q, R, S , C rarr P, Q, R, D rarr P, Q, R,`
Orbital angular momentum
`(L)=sqrt(l(l+1))(h)/(2pi)" "` i.e. L depends on azimuthal quantum number only.
B. To describe a one electron wave function, three quantum numbers n, l and m are needed. Further to abide by Pauli exclusion principle, spin quantum number(s) is also needed.
C. For shape, size and orientation, only n, l and m are needed.
D. Probability density `(Psi^(2))` can be determined if n, l and m are known.
