WebThe 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. WebIn the Bohr model, the wavelength associated with the electron is given by the DeBroglie relationship. and the standing wave condition that circumference = whole number of wavelengths. In the hydrogenic case, the number n is the principal quantum number. These can be combined to get an expression for the angular momentum of the electron in orbit.
