The specific energies of these components vary with the specific energy state and the substance. Energy level diagrams. There are various types of energy level diagrams for bonds between atoms in a molecule. Examples See more A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy, called energy levels. This contrasts with classical particles, which can have any … See more The first evidence of quantization in atoms was the observation of spectral lines in light from the sun in the early 1800s by Joseph von Fraunhofer and William Hyde Wollaston. … See more Chemical bonds between atoms in a molecule form because they make the situation more stable for the involved atoms, which generally means the sum energy level for the involved atoms in the molecule is lower than if the atoms were not so bonded. As … See more Crystalline solids are found to have energy bands, instead of or in addition to energy levels. Electrons can take on any energy within an unfilled band. At first this appears to be an … See more Quantized energy levels result from the wave behavior of particles, which gives a relationship between a particle's energy and its wavelength.
