Document Summary

An orbit in the bohr model describes a well defined circular path for an electron. Photon energy exactly equals gap between levels. Small energy gap, low frequency, long wavelength. High energy gap, high frequency, short wavelength. Introduced connection between spectra and electron structure. Does account for observed spectra of multielectron elements or ions. Movement of electrons in atoms is much less clearly defined. Both matter and energy are alternate forms of the same entity. Exhibit dual characteristics of particles and of waves. This model allows a better understanding of the behavior of tiny particles such as electrons. A mathematical function that describes the position of the electron-wave in three dimensions near nucleus. Movement of the electron is described by a wave function. All matter behaves as though it moves in a wave. The motion of any particle can be described by the de broglie equation.
