The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
The quantity n is called the principal quantum number, and is an integer; n = 1, 2, 3,. Inserting values for n into the energy equation gives the energies of all allowed orbits shown in Figure 7.11 of the text. The radius of each electron orbit in the hydrogen atom is proportional to n2. As n increases, the orbit radius increases rapidly. The farther the electron is from the nucleus, the higher its energy.
