The number of orbitals associated with quantum numbers n = 5 , m s = + 1 2 is:

Options

  1. A11
  2. B25
  3. C50
  4. D15

Correct answer

B. 25

Step-by-step solution

For n=5 5s,   5p,   5d,   5f   and 5 g and subshell is available In 5 s → 1   orbital 5 p → 3   orbital 5d → 5 orbital 5f → 7   orbital 5 g → 9   orbital In each subshell 1 electron of every orbital will belong to m 5 = + 1 2 So, Total number of orbitals that will be associate with m 5 = + 1 2 will be 1 + 3 + 5 + 7 + 9 = 25
