example: what are the first two quantum numbers for the electrons located in subshell 2p?energy level (n = 2), p subshell (l = 1)

what are the first two quantum numbers for the electrons located in subshell 4d?

Energy level (n = 4), d subshell (l = 2)  

Step-by-step explanation:

The number in 4d tells you the energy level of the subshell: n = 4.

The letter d gives you the secondary quantum number l.

Depending on its value, the letter gives you the shape of the orbital.

l = 0 corresponds to an s orbital (spherical)

l = 1 corresponds to a p orbital (dumb-bell shaped)

l = 2 corresponds to a d orbital (four four-leaf clovers + one that looks like a dumbbell with a doughnut around its middle)

the answer is 0.8m.
