### Energy spectrum

Why is it that the hydrogen spectrum doesn't have equal differences between states (n=1 to n=2 is a lot bigger than the differences between any other energy levels)?

Each line represents a different jump in energy that an electron of an atom could make. The energy difference between these levels is given by the Rydberg formula.

This is because the Bohr model only works with hydrogen. It does not correspond to other energy levels, so these other energy have different properties than the first. Since hydrogen atoms have only one electron, they contains a large number of shells, thus when one electron jumps from one shell to another, a photon is released and the energy difference of the shells causes different wavelengths.

You can also see it in the Rydberg formula that E is proportional to n-2

### Re: Energy spectrum

The energy levels were found experimentally so they are not perfect like we would imagine if we just came up with the idea. Because Hydrogen only has one electron, it would make sense that the first shell has the highest energy, and every subsequent shell after that has less.
