Question

Which of the following quantum numbers is not used for gaining knowledge about orbitals ?

(A) n

(B) l

(C) ms

(D) ml​

Answer 1

Answer:

Question:

Which set of quantum numbers cannot specify an orbital?

a. n = 3, l = 2, ml = 2

b. n = 2, l = 1, ml = -1

c. n = 3, l = 2, ml = 3

d. n = 4, l = 3, ml = 0

Quantum Numbers:

There is a set of four main quantum numbers that represent an electron's shell, subshell, orbital, energy, and spin.

These four main quantum numbers are principal quantum number (n), Azimuthal quantum number (l), magnetic orbital momentum quantum number (ml), and magnetic spin quantum number (ms).

Answer and Explanation:

For a given value of the Azimuthal quantum number l, there can be (2l+1) values of the magnetic orbital momentum quantum number ml that range from -l t +l.

Thus, for l = 2, the possible values of ml are -2, -1, 0, +1, +2.

Thus, the set in option (c) is not correct.
