Bohr calculated the … WebBohr’s model of the hydrogen atom provides insight into the behavior of matter at the microscopic level, but it does not account for electron–electron interactions in atoms with more than one electron. It does introduce several important features of all models used to describe the distribution of electrons in an atom.

WebThe postulates of Bohr's model of an atom are 1. Electrons revolve around the nucleus of an atom in a certain definite path called the Orbit or stationary state of the shell. WebConsider an electron starting at rest, far from the atom, and ending in a stable closed orbit (itself a bold assertion, since classically there are no such orbits). Since the starting "frequency" is 0, Bohr splits the difference and postulates that the radiated emission's frequency $\nu_r$ is half the frequency of the end orbit $\nu_c$.
