2.31 Which of the following subshells cannot exist in an atom: (a) 2d; (b) 4d; (c) 4g; (d) 6f?

2d and 4g cannot exist
the 2 sublevel only has s and p
the 4 sublevel only has s p d f

For (a), one must remember that subshells are the principal and angular momentum quantum numbers. The symbol for the two would be (n) and (l), with l=n-1.
a.) cannot exist because if n=2, values of l can be l=1 or l=0. l=1 is the p-orbital and l=0 is the s-orbital; there is no value of l that can be a d-orbital

For (b), one can apply the same method
b.) can exist because n=4, values of l must be l=0,1,2,3. l=2 is the d-orbital

Hope that helps!
