Atomic models

J J Thomson

-Him measurements of charge and mass showed that an atom must contain smaller,negativly charged particles-he called them 'corpuscles'

-He created the 'Plum Pudding' model with negativly charged eletrons embedded in a positivly charged sphere.

Rutherford

-Rutherford fired positivly charged Alpha particles into a thin sheet of gold.

-Due the the 'Plum Pudding' model,slightly Rutherfod expected most of the particles to be deflected very slightly as the 'positive pudding' made up most of the atom.

-However, most particles passed straight through the…
