We’re being asked to**identify the variety of orbitals**had in the**3rd major level (n = 3)**.

You are watching: How many orbitals (total) are contained in the third principal level (n=3) of a given atom?

Recontact that the** quantum numbers**that specify an electron are:

•*Principal Quantum Number***(n)**: deals with thedimension and also energy of the atomic orbital.

Thepossible values for nare**1 to ∞**.

•*Angular Momentum Quantum Number***(l)**: deals with theform of the atomic orbital.

Thepossible worths for lare**0 to (n – 1)**.

•*Magnetic Quantum Number***(ml)**: faces theorientation of the atomic orbitalin 3D space.

Thepossible worths for mlare the selection of l:**–l to +l**.
