Which of the following arrangements is possible?

Which of the following arrangements is possible? 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=5n=5, then l=0,1,2,3,4l=0,1,2,3,4. Again when l=2l=2, then m=−2,−1,0,+1,+2m=-2,-1,0,+1,+2. The ' ss ' value can be ±1/2\pm 1 / 2 Hence the arrangement, n=5,l=2,m=2,s=+1/2n=5, l=2, m=2, s=+1 / 2 is possible for an electron.
