WebSo, we have the energies for three different energy levels. The energy for the first energy level is equal to negative 13.6. E two is equal to negative 3.4, and E three is equal to negative 1.51 electron volts. So energy is quantized using the Bohr models, you can't have a value of energy in between those energies. WebWe like representing these energy levels with an energy level diagram. The energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time.
