Which of the following is not permissible arrangement of electrons in an atom?
Options
(a) n = 5, l = 3, m = 0, s = +1/2
(b) n = 3, l= 2, m= –3, s = – 1/2
(c) n = 3, l= 2, m= –2, s = – 1/2
(d) n = 4, l = 0, m = 0, s = – 1/2
Correct Answer:
n = 3, l= 2, m= –3, s = – 1/2
Explanation:
m=2l+1, thus for l=2, m=5, hence values of m will be -2,-1,0,+1,+2. Therefore for l=2, m cannot have the value of -3
