WebThe “electrons” in the atom are not fixed in their orbits; they can move freely around the nucleus. According to Bohr, this is what provides energy in the atom. Describe Bohr’s Model of the Atom. Bohr describes Bohr’s model of the atom by the electron’s orbit as a “planetary” or “cloud-type” system because of its shape. WebIn 1913, Danish physicist Niels Bohr applied Max Planck’s quantum theory to the nuclear atom of Ernest Rutherford, thus formulating the well-known planetary model of the atom, wherein electrons orbit a central nucleus in well-defined levels of energy ( Figure 1 ). Note that Bohr stated that electrons in the atom follow elliptical orbits (not ...
