The relation between n m ( n m = the number of permissible values of magnetic quantum number ( m ) ) for a given value of azimuthal quantum number l , is

Options

  1. An m = l + 2
  2. Bl = n m - 1 2
  3. Cl = 2 n m + 1
  4. Dn m = 2 l 2 + 1

Correct answer

B. l = n m - 1 2

Step-by-step solution

The possible magnetic quantum number values for a given value of azimuthal quantum number l are - l   to   + l through 0 . Suppose if l = 1 , the possible n m values are - 1 , 0 , + 1 . The mathematical formula can be written as follows, n m = 2 l + 1 ⇒ l = n m - 1 2
