Which of the following arrangements is possible?

Options

  1. A(a)
  2. B(b)
  3. C(c)
  4. D(d)

Correct answer

A. (a)

Step-by-step solution

When n=5 , then l=0,1,2,3,4 . Again when l=2 , then m=-2,-1,0,+1,+2 . The ' s ' value can be 1 / 2 Hence the arrangement, n=5, l=2, m=2, s=+1 / 2 is possible for an electron.
