Question #221304

How many orbitals are associated with the p-sub energy level

Expert's answer

The p sublevel has 3 orbitals, so can contain 6 electrons max.

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

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

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

, which in turn depends on the *principal quantum number*, n

.

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 n>1, since the first energy level only has an **s-sublevel**.

Therefore, s-sublevel has a total of **three p-orbitals**: px, py, and pz

.
