Document Summary
Quantum numbers have the following restrictions: is any positive integer. ranges from 0 to ranges from to can be either +1/2 or 1/2. The bohr equation states that the energy of an electron in a particular orbit is given by. R = 1. 097 107 (the rydberg constant) h = 6. 626 10 34 (planck"s constant) c = 2. 998 108 (the speed of light in a vacuum) and n is the electron configuration number. The energy of the photon emitted by the electron is related to its wavelength by. E= hc where is the wavelength in meters. Electrons are emitted from the surface of a metal when it"s exposed to light. Each metal has a certain threshold frequency of light, below which nothing happens. Right at this threshold frequency, an electron is emitted. Above this frequency, the electron is emitted and the extra energy is transferred to the electron.
