If an electron has a principal quantum number (n)of 7 and an angular momentum quantum number (l)of 3,the subshell designation is ________.
A)7f
B)7s
C)7p
D)3f
E)3d

Question

Quizplus · Accepted Answer

The subshell designation is determined by the angular momentum quantum number (l), where l=0 corresponds to s, l=1 to p, l=2 to d, and l=3 to f. Therefore, with l=3, the subshell is f, and with a principal quantum number (n) of 7, the correct designation is 7f.
