Explain what each quantum number in a quantum number set tells you about the electron. compare and contrast the locations and properties of two electrons within an atom that have the quantum number sets (2, 1, 0, +½) and (2, 0, 0, +½).

This is a bit long right now.

(n l m s) these are the numbers.

n=2, second orbital level.
l is the type of orbit: l=1 elongated, l=0 spherical
m=0, magnetic number: 0
s=spin, both have spin positive

You need still to round it up. Srry!

The first electron is in the n=2 shell, the p subshell (l=1), m sub l = 0 so it is in the middle space of its subshell's energy level diagram. It has a positive spin.

The second electron is in the n=2 shell, is in the s subshell (l=0), m sub l = 0 so it is in the middle space of its subshell's energy level diagram. It also has a positive spin.

Ithink the answer is a or d.
