A higher value of n signifies greater energy and a larger orbital size, which directly correlates with the electron's potential energy and its shielding effect. Angular Momentum Quantum Number (l) Building upon the principal quantum number, the angular momentum quantum number l (ranging from 0 to n -1) defines the subshell and the geometric shape of the orbital.

The Four Quantum Numbers To fully describe an electron in an atom, four distinct quantum numbers are required, each corresponding to a specific physical property. This set of identifiers provides a complete description of an electron's energy, shape, orientation, and spin direction.
Consequently, the s subshell (l=0) contains one orbital and holds 2 electrons, the p subshell (l=1) contains three orbitals holding 6 electrons, the d subshell (l=2) holds 10 electrons across five orbitals, and the f subshell (l=3) accommodates 14 electrons across seven orbitals. Principal Quantum Number (n) The principal quantum number, denoted as n , is the primary determinant of an electron's energy level and average distance from the nucleus.
