Which of the following is not permissible arrangement of electrons in an atom?

Multiple Choice Options

  • A n=5, l=3, m=0, s=+1/2n=5,\ l=3,\ m=0,\ s=+1/2
  • B n=3, l=2, m=−3, s=−1/2n=3,\ l=2,\ m=-3,\ s=-1/2
  • C n=3, l=2, m=−2, s=−1/2n=3,\ l=2,\ m=-2,\ s=-1/2
  • D n=4, l=0, m=0, s=−1/2n=4,\ l=0,\ m=0,\ s=-1/2

Step-by-Step Verified Solution

In an atom for any value of n, the values of l = 0 to (n-1) For a given value of l, the values of m l = - l to 0 to + l and the value of s = +1/2 or -1/2 In option(b), l = 2 and m l = -3 This is not possible. as for l = 2 min value of m l = -2
