We’re being asked toidentify the variety of orbitalshad in the3rd 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 thequantum numbersthat specify an electron are:

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

Thepossible values for nare1 to ∞.

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

Thepossible worths for lare0 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.
