The Bohr Model, created by Niels Bohr and Ernest Rutherford, depicts an atom in planetary form. The electrons orbit the nucleus in an orderly fashion. It easily represents valence electrons and energy levels, but is flawed from evidence of quantum mechanics. Now, electrons have be known to move wildly within the cloud. They follow probability, instead of patterned function. Helmenstine, Anne Marie. "Review the Bohr Model of the Atom." About.com Education. N.p., 22 July 2016. Web. 01 Oct. 2016.
