Which two of the four quantum numbers determine the energy level of an orbital in a multielectron atom? Which two of the four quantum numbers determine the energy level of an orbital in a multielectron atom? nn and ll nn and mlml ll and mlml

The correct answer is - n and l.

Explanation:

The size of an orbital is determined by the principal number of shell which is represented by n. The larger the energy level (n) bigger the size of the orbital. N can be any integer value: 1, 2, 3 . . . . and so on.

l represents the angular momentum or subshell number provides the overall shape of an orbital in this subshell only integer values between 0 and n-1 are permitted.

Thus, n & l are two quantum numbers that determine the energy level of an orbital in a multielectron atom.
