We think of an atom like this. Having electron shells at equal distances apart

We think of an atom like this. Having electron shells at equal distances apart. If it was like this then surely the lines in the spectra would be equally spread out. The line emission spectra tells us something different.

Electron shells

Electron shells . Electrons move rapidly around the nucleus in areas called shells. Each shell can hold up to 8 electrons except the first shell which can only hold 2 electrons The number of the period (row) an element is in, is the same as the number of shells it has.
