This final digit describes the intrinsic angular momentum, or "spin," of the electron. Understanding the specific parameters that define an electron's position and energy within an atom is fundamental to grasping atomic structure.
Valid Quantum Numbers Visual Guide: Understanding the Complete Set
Valid Combinations and the Pauli Exclusion Principle. Principal Quantum Number (n) The first number in the sequence is the principal quantum number, denoted as n.
These identifiers work in concert, building upon one another to narrow down the electron's location and movement from the broadest energy level to the most specific orbital orientation. Consequently, for the second energy level where n is 2, l can only be 0 or 1.

Because it represents a count of shells, this number must always be a positive integer, meaning it can be 1, 2, 3, and so on, but never zero or a fraction. As n increases, the electron occupies a higher energy level and resides farther from the nucleus.
