Which of the following statements are correct

Options

A. The angular momentum of an electron due to its spinning is given as `sqrt(s(s+1)) h/(2pi)` (where s can take the value of 1/2)
B. The angular momentum of an electron due to its spinning is given as` m_s` (h/` 2 pi` )where `m_s` can take the value of +1/2.
C. According to Pauli.s exclusion principle, no two electrons in an atom can have the same values of quantum numbers n, I and m
D. The azimuthal quantum number cannot have negative values.

Answer

A, D

Explanation

b) The expression `m_s (h//2pi)` is that of z-component of angular momentum.
c) The correct statement is as follows - No two electrons is an atom can have the same values of all the four quantum number n, l , m and `m_s`.
d) The azimuthal quantum number has the value 0 , 1, 2 ......, (n-1).
