Write the subshell notation (3d, for instance) and the number of orbitals having the following quantum numbers: (a) n=5, l=2; (b)n=1, l=0; (c) n=6, l=3; (d)n=2, l=1.

Please do not title your response as the question number. Instead, title as the topic, such as atomic orbitals. Also, do not just post the straight up question. Instead, ask what part of the question you do not understand. Like what n and l represent? How they go together?

Thank you.

The n represents the principle quantum number that determines energy and size. It is also called the shell, and it corresponds with the row number for an atom on the period table as well as the coefficent of the subshell notation. The l represents the angular momentum quantum number, where l = 0 is the s-orbital, l = 1 is the p-orbital, l = 2 is the d-orbital, and l = 3 is the f-orbital. Using this, we can determine the subshell notation.

a. 5d
b. 1s
c. 6f
d. 2p

Hope this helps!
