What quantum numbers specify these subshells?

Imagine a universe in which the four quantum numbers can have the same possible values as in our universe except that the angular-momentum quantum number l can have integral values of 0, 1, 2...n + 1 (instead of 0, 1, 2..., n - 1). (a) How many elements would be in the first two rows of the periodic table in this universe?

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

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

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