(Here: Include Name of Scientist as a Title)
Ernest Rutherford
Year Model was Proposed: 1911

Nickname for this model: Rutherford Model

Description of Model:

Include a brief description of the model proposed by this scientist. Also include a brief summary of the experiment done by the scientist to discover this model.
he postulated that atoms have their positive charge concentrated in a very small nucleus,[3] and thereby pioneered the Rutherford model, or planetary, model of the atom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment.

Atomic structure/structures discovered by this model: He was the first one to
prove that radioactivity involved the transmutation of one chemical element to another, and also differentiated and named alpha and beta radiation.

How did this model build on the previous model?
JJ thought that electrons were evenly embedded throughout a positively charged sphere, and the Rutherford thought that almost all the mass of an atom, and all its positive charges were concentrated in a centeral atomic nucleus surrounded by electrons.
