The set of Quantum numbers that is not possible for a d-electron
`(A) n=3, l=2, m=0, s=+1/2`
`(B) n=2, l=2, m=-2, s=+1/2`
`(C) n=4, l=2;m=+2, s=+1/2`
`(D) n=4, l=2, m=-1, s=-1/2 `

Text Solution

Verified by Experts

`(B)` because the given orbital is `2d` and this cannot exist because `n=2` can have l in the range `[0,n-1]` and clearly `n-1` is not equal to `2`
