Question

Two electrons are found in the same atom. One has the quantum number set (3, 2, 0, +½), and the other has the quantum number set (3, 1, 0, +½). They share the

same sublevel, but are in different orbitals.

same orbital, but have different spin directions.

same energy level, but are in different sublevels.

same type of sublevel, but are found in different energy levels.

Answer 1

3 indicates both are at same energy level.
+1/2 indicates both have same spin.
0 indicates that both are in same sublevel.
The difference occurs at the 2nd number which indicates that they are in different orbitals.

So, option 1 is correct.
