How many electrons can be described by the following quantum numbers: n=2, 1=-1, m-1.
SIZIF [17.4K]

Answer:

6 electrons

Explanation:

The principal quantum number n; describes the energy level and here, it is 2.

The azimuthal or secondary quantum number l is given as 1, we are describing the p-orbital

The magnetic quantum number is -1, and we have 3 sub-orbitals here:

   It is a 2p-suborbital

So; in each sub orbital we have 2 electrons

The number of electrons that can be described here  =  2 x 3 = 6 electrons.
