    Solution:

    The quantum number determines the number of angular nodes in an atomic orbital is l.

    The entire description of a particular electron belonging to an atom may be expressed in terms of four quantum numbers, which are: Principal quantum number, indicated by the letter n. l stands for the azimuthal quantum number, also known as the orbital angular momentum quantum number.
