We’re gift asked to**determine the number of orbitals**contained in the**third primary level (n = 3)**.

You are watching: How many orbitals are contained in the third principal level

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

•*Principal Quantum Number***(n)**: faces thesize and energy that the atom orbital.

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

•*Angular momentum Quantum Number***(l)**: encounters theshape that the atomic orbital.

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

•*Magnetic Quantum Number***(ml)**: deals with theorientation of the atom orbitalin 3D space.

Thepossible worths for mlare the variety of l:**–l come +l**.
