Absportpion/Emission Spectra

Colors relate to energy absorbed/released

​the specific amount of energy emitted or absorbed by electrons moving between energy levels

​A Quantum of Energy

Bohr calculated the energy of a hydrogen electron...

Here, E is the energy of an electron and n is an integer that corresponds to the energy level where the electron is located.
