# How many orbitals in a p sublevel?

##### 1 Answer

Three.

#### Explanation:

The number of orbitals you get *per sublevel* is given by the **magnetic quantum number**,

More specifically, the number of orbitals you get for a given sublevel depends on the number of values that

The magnetic quantum number depends on the value of the *angular momentum quntum number*, *principal quantum number*,

SImply put, the principal quantum number gives the energy level on which the electron resides, the angular momentum quantum number gives you the **sublevel**, and the *number of values* you have for the magnetic quantum number gives you the number of orbitals you get per sublevel.

So, in order to have a **p-sublevel**, you need to have **s-sublevel**.

The angular momentum quantum number can take values in the range

#l = 0, 1, 2, n -1#

The magnetic quantum number can take values in the range

#m_l in { -l, ..., 1, 0, 1, ..., l}#

A **p-sublevel** is characterized by

#m_l = { -1, 0 ,1}#

Therefore, the p-sublevel has a total of **three p-orbitals**:
