Describe bohr model of an atom
WebThe Bohr Model of The Atom. 1) The H atom only has certain energy levels, they are determined by fixed circular orbits of electrons around the nucleus. 2) An atoms energy does not change while the electron moves in a particular orbit. 3) Electron changes to another energy level (orbit) by absorbing or emitting a photon. WebSep 16, 2024 · Bohr’s model was not able to define the effect of magnetic field and electric field on the spectra of atoms. The Bohr atomic model made correct predictions for smaller-sized atoms like hydrogen, but poor spectral predictions were obtained when larger atoms are considered.
