We started our new unit today about Atomic Structure and Radioactivity. We began exploring some theories about the structure of the atoms and the experiments done to prove these theories.
Thomson discovered the electron by using a cathode ray tube to show atoms of an element emit particles with a negative charge. He made the chocolate chip cookie model
Rutherford discovered the proton through his gold foil experiment and proved the presence of a positively charged center in an atom. A visual representation of this is:
