WebAs a biochemist, I use fluorophores daily but I've realized I don't entirely understand the underlying physics. If fluorescence is a result of excited electrons emitting photons, why are emission spectra shown as continuous? Shouldn't only certain emission wavelengths be allowed based on electron energy states? WebApr 14, 2024 · It confirms the prediction of quantum theory that electrons occupy only discrete, quantized energy states. This experiment supports Bohr model of atom. ... As a result, the energy level of electron bound to the atom is raised. Now the electron almost loses its energy, and measured current drops. Franck-Hertz Data for Mercury .

WebFigure 30.16 The planetary model of the atom, as modified by Bohr, has the orbits of the electrons quantized. Only certain orbits are allowed, explaining why atomic spectra are discrete (quantized). The energy carried away from an atom by a photon comes from the electron dropping from one allowed orbit to another and is thus quantized. WebThe orbital angular momentum of electrons in atoms associated with a given quantum state is found to be quantized in the form. This is the result of applying quantum theory to the orbit of the electron. The solution of the Schrodinger equation yields the angular momentum quantum number. Even in the case of the classical angular momentum of a ...

WebQuantization of orbital energy is caused by the wave nature of matter. Allowed orbits in atoms occur for constructive interference of electrons in the orbit, requiring an integral number of wavelengths to fit in an orbit’s circumference; that is, nλ n = 2πr n (n = 1, 2, 3 ...), where λ n is the electron’s de Broglie wavelength.

WebThe energy of each quantum of electromagnetic radiation is E = h ν, where ν is the frequency of electromagnetic radiation, and h = 6.626 × 10 − 34 J s.
