There are only two subshells associated with the n=2 shell of an atom

What is the angular-momentum quantum number (also called the azimuthal quantum number), ℓ, for the orbital shown here?

What is the correct representation for the subshell with n = 2 and l = 1?

2p 1p 1d 2d

Provide all the possible values of l for a 2 energy level.

How many sublevels are contained in the third shell (n = 3) for a given atom?

Which of the following orbitals possesses the most orbital shapes?

The contour representation of one of the orbitals for the n = 3 shell of a hydrogen atom is shown here. (a) What is the quantum number l for this orbital?
