We´re asked to determine how many electrons are in a set of quantum numbers given. To solve this problem, let’s first **define and determine the possible values of the four quantum numbers**:

• **principal quantum number (n) ****→** energy level in orbitals and its value could be **any positive integer **starting from 1 to infinity.

• **angular momentum quantum number (****ℓ****)**** → ****(l) has to be at least 1 less than n, **range of values from** 0 up to (n-1)**

▪ Each **ℓ**** value** corresponds to a **subshell**:

How many electrons are in n = 3, l = 2?
