Which set of quantum numbers cannot specify an orbital?

Suppose that, in an alternate universe, the possible values of ml are the integer values including 0 ranging from -l -1 to l +1 (instead of simply -l to +l). How many orbitals exist in each sublevel? a. s sublevel b. p sublevel c. d sublevel

What are the possible values of m_ℓ for an electron in a d orbital?

Suppose that, in an alternate universe, the possible values of ml were the integer values including 0 ranging from −l−1 to l+1 (instead of simply −l to +l). how many orbitals would exist in each of the following sublevels?
