Final answer:
The azimuthal quantum number, represented as l, corresponds with the approximate geometric shape of an orbital and describes the electron cloud's shape within an atom.
Step-by-step explanation:
The azimuthal quantum number, often symbolized as l, is one of the quantum numbers used to characterize the state of an electron in an atom. Its value describes the approximate geometric shape of the electron distribution, or orbital, in which an electron is most likely to be found. For a given principal quantum number, n, the azimuthal quantum number can have integral values from 0 to n - 1. Each value of l corresponds to a specific subshell (s, p, d, f, etc.), which in turn dictates the shape of the electron cloud.
