Derivation of Bohr`s Equations for the One
... Since ao is a constant, equation (6) predicts that the radius increases in direct proportion to the square of the quantum number, n2, and decreases in inverse proportion to the atomic number, Z. Thus, the sizes of the orbits in hydrogen are predicted to be ao, 4ao, 9ao, 16ao, 25ao, etc. Furthermore, ...
