Document Summary
The allowed values of n are positive integers (n = 1, 2, 3, 4, etc) The organization of the periodic table is intimately related to the organization of electrons in atoms, which can be expressed in terms of quantum numbers. Quantum numbers refers to a series of numbers that results from solving schr dinger"s wave equation for the hydrogen atom. Three quantum numbers are used to characterize an orbital. The principal quantum number ( n ) describes the size and energy of the shell in which the orbital resides. The angular momentum quantum number ( l ) indicates the shape of the orbital. For any given value of n, l can have values that range from 0 to (n-1). For example, in the n = 4 shell, has values of 0, 1, 2, and 3. Each value of corresponds to an orbital label and an orbital shape.
