# How many electrons can have #n = 4# and #m_l = 2#?

##### 1 Answer

The maximum number of electrons that can have those two values for **4**.

You are given the values for **principal quantum number**, and **magnetic quantum number**, so you must first determine how many *orbitals* can have these two values for their respective quantum numbers, then determine how many *electrons* can each of those orbitals hold.

The value of **angular momentum quantum number**, which in turn depends on the value of

For **n = 4**, only two values for **2**,

This means that you get *two orbitals* that match those two quantum numbers

**4d-orbital**;

**4f-orbital**;

Since each of the two orbitals can hold a maximum of two electrons, the maximum number of electrons that have those two quantum numbers will be **4**
