Answer:

Choose whichever quantum number it is below.

Explanation:

The principal quantum number, #n# would be #n=2#

The angular quantum number, #l#, describes the sublevels in #n# and the orbital shapes.
So #n=2# has 2 sublevels called 2s and 2p
i.e. angular quantum number= 2

The magnetic quantum number, #m# describes the number of orbitals withing a sublevel.

So the #p# sublevel in #2p# has 3 orbitals (with up to 6 elecrons) ie. magnetic quantum number= 3
