How many orbitals have the values n_3=4 and l_3=3 ?

How many orbitals have the values n=4, l=3, and ml=-2?

I don't know what n3=4 and l3=3 mean.

Two electrons can have the value of n=4, l =3, ml = -2.

n sub 3 equals 4. l sub 3 equals 3.

To determine the number of orbitals with specific quantum numbers, we can use the following equations:

For n and l values:
Number of orbitals = (2 * l) + 1

For n, l, and ml values:
Number of orbitals = 1

Now let's find the answers to your questions:

1. For the quantum numbers n_3 = 4 and l_3 = 3:
Number of orbitals = (2 * l_3) + 1
= (2 * 3) + 1
= 6 + 1
= 7
So, there are 7 orbitals with n = 4 and l = 3.

2. For the quantum numbers n = 4, l = 3, and ml = -2:
Number of orbitals = 1 (since ml specifies a specific orbital within a subshell)
So, there is 1 orbital with n = 4, l = 3, and ml = -2.

Remember, in the case of n, l, and ml values, the number of orbitals is always 1, regardless of the specific values of n, l, and ml.
