Question

If \(n,l,m\) and \(s\) represent the symbols of quantum numbers, the impossible quantum number set for the electron in terms of \(n,l,m\) and \(s\) respectively is

• A. \(2,0,-1,+\frac{1}{2}\)
• B. \(3,0,0,-\frac{1}{2}\)
• C. \(4,1,+1,+\frac{1}{2}\)
• D. \(3,2,-1,-\frac{1}{2}\)

Hint:

For a given \(l\), magnetic quantum number \(m\) can take values from \(-l\) to \(+l\). If \(l=0\), then only \(m=0\) is possible.

Answer 1

The Correct Option is A
