Question

Give the set of four quantum numbers that could represent the electron gained to form

the Br ION from the Br atom.
A. n = 4 I = 1 mₗ = -1 mₛ = +1/2
B. n = 4 I = 0 mₗ = 1 mₛ = +1/2
C. n = 4 I = 2 mₗ = 1 mₛ = -1/2
D. n = 3 I = 2 mₗ = 1 mₛ = +1/2
E. n = 5 I = 1 mₗ = -1 mₛ = -1/2

Answer 1

The set of four quantum numbers that could represent the electron gained to form the Br ion from the Br atom is n = 4, l = 1, m₁ = -1, and ms = +1/2.

Step-by-step explanation:

The set of four quantum numbers that could represent the electron gained to form the Br ion from the Br atom is option A: n = 4, l = 1, m₁ = -1, and ms = +1/2.

Quantum numbers provide important information about the energy and spatial distribution of an electron. The principal quantum number (n) represents the energy level or shell, the azimuthal quantum number (l) represents the subshell or shape, the magnetic quantum number (m₁) represents the orientation, and the spin quantum number (ms) represents the spin state of the electron.

In this case, the electron gained to form the Br ion from the Br atom is in the 4th energy level (n = 4), in the p subshell (l = 1), with an orientation of -1 (m₁ = -1), and a spin state of +1/2 (ms = +1/2).
