Question

for a given atom of n=3,l=2,m2-1,S=+1/2 what could be the atomic number and the electronic configuration ​

Answer 1

Only one electron in a given atom can have the set of quantum numbers given in the question.

Explanation:

No two electrons in an atom can have the same set of quantum numbers.

The first quantum number is the principle quantum number , which is

n=3

This means the electron is in the third energy level (shell).

The second quantum number, the angular momentum , is

l=2

and means the electron is in the

d sublevel (subshell).

The third quantum number, the magnetic quantum number ,

m1=2

represents one of the five

3d orbitals.

Lastly, we have the spin quantum number ,

m2=+1/2

It indicates the direction of the spin of the electron.
