SATHEE: Atomic Structure Question 380

Atomic Structure Question 380

Question: 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) $n = 4, l = 0, m = 0, s = - 1 / 2$

Show Answer

Answer:

Correct Answer: B

Solution:

$m = - l$ to $+ l$ , through zero thus for $l = 2$ , values of m will be $- 2, - 1, 0, + 1, + 2.$ Therefore for $l = 2$ , m cannot have the value -3.
