DetailsPlanetary Atom Pendant _Designed by 3P3D ( http://www.thingiverse.com/thing:90239 ) _Comments written by designer :"These spectacular looking pendants are a depiction of the atomic planetary model. It shows the paths of 3 electrons in orbit around the nucleus. It is geeky yet very stylish and anyways, nerdy is definitely a winning trend at the moment. Great for anyone interested in science. Don't miss out on this amazing piece of jewelry! " _***The Rutherford model is a model of the atom devised by Ernest Rutherford. Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that the so-called "plum pudding model" of J. J. Thomson of the atom was incorrect.Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny, heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. _Rutherford's model deferred to the idea of many electrons in rings, per Nagaoka. However, once Niels Bohr modified this view into a picture of just a few planet-like electrons for light atoms, the Rutherford-Bohr model caught the imagination of the public. It has since continually been used as a symbol for atoms and even for "atomic" energy (even though this is more properly considered nuclear energy).
