Question

An electron that has the quantum number n-3 and m -2​

Answer 1

Given:

Electron has quantum numbers n = 3 , m = 2.

To find:

Orbital occupied by the electron.

Calculation:

Principal Quantum Number (n) signifies the orbit or shell in which the electron is placed.

n = 3 , means that the electron is placed in 3rd orbit.

Now , Magnetic Quantum Number (m) gives the relative position of the electron in orbitals.

Relation between Magnetic Quantum Number and Azimuthal Quantum Number (l)

$\sf{m \: = - l \: \: to \: + l}$

$= > l = |m|$

$= > l = |2|$

$= > l = 2$

Hence the electron is placed in d orbital.

So, final answer is:

Electron is placed in 3rd orbit , d orbital
