Question

fill in the blank question
each major energy level, specified by n, is called a energy level.

Explanation:

In atomic structure, the quantum number \(n\) is used to denote the principal energy level. Each value of \(n\) (e.g., \(n = 1,2,3,\cdots\)) corresponds to a different major energy level. The principal energy level describes the average distance of an electron from the nucleus and its energy.

Answer:

principal
