The Bohr Model of the hydrogen atom proposed that there were very specific energy states that the electron could be in. These states were called stationary orbits or stationary states. Higher energy states were further from the nucleus. These orbits were thought to be essentially spherical shells in which the electrons orbited at a fixed radius or distance from the nucleus. The smallest orbit is represented by n=1, the next smallest n=2, and so on, where n is a positive...

In lab we studied the Bohr model of the hydrogen atom which is verified exactly with quantum mechanical calculations. From quantum mechanics we also find that Bohr’s equation can be used for any one-electron cation like He+, Li2+, Be3+ etc, by including the atomic number, Z, of the cation in the equation with Bohr’s constant (): En= -Z2n2(Accurate for any one-electron cation with atomic number Z) Use this equation to calculate the energy (J) of the first and second energy...
