A sodium chloride molecule has an Na-Cl distance of 236.1 pm (recall 1 pm is 10-12 m.) In this ionic molecule, the effective
charges of the ions are +1.3x10-19 C for the Na and -1.3x10-19 C for the Cl (the charge is a little less than the charge of an
electron because the chlorine doesn't remove the electron from the sodium completely, sharing it just a little bit.)

LEDs are semiconductor devices in which the electrons can exist only in certain energy levels. Much like molecules, the energy levels are packed together close enough to form what appears to be a continuous band of possible energies. Energy supplied to an LED in a circuit excites electrons from a valence band into a conduction band. An electron can emit a photon by undergoing a quantum jump from a state in the conduction band into an empty state in the valence band, as shown. The size of the band gap ΔEband determines the possible energies— and thus the wavelengths—of the emitted photons. Most LEDs emit a narrow range of wavelengths and thus have a distinct color. This makes them well-suited for traffic lights and other applications where a certain color is desired, but it makes them less desirable for general illumination. One way to make…arrow_forward
