Thomson was an English scientist He discovered the electron when Atomic Structure he was experimenting with gas discharge tubes. He noticed a movement in a tube. He called the movement cathode rays. The rays moved from the negative end of the tube to the positive end. He realized that the rays were made of negatively charged particles - electrons.

11:15 .l .l 5.00 KB/S A O (12 4 app.teachermade.com/fill/13c37t (4) C Q Q T TI 4 v Save for Later I'm Done A. John Dalton was an English chemist. His Dalton's Atomic Theory ideas form the atomic theory of matter. Here are his ideas. • All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. • All atoms of the same elements are alike. (One Atoms of element X Atoms of ement Y Compound of elemeite XandY atom of oxygenis like another atom of oxygen.) • Atoms of different elements are different. (An atom of oxygen is different from an atom of hydrogen.) • Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios. For example, water is a compound made up of 2 atoms of 1. What is the name of John Dalton's theory? 2. What are elements made of? 3. An atom of hydrogen and an atom of carbon are 4.

Why do electrons move from the negative end of the tube to the positive end? s. What was Thomson working with when he discovered the cathode rays?| Ernest Rutherford conducted a famous experiment called the gold foil experiment. He used a thin sheet of gold foil. He also used special equipment to shoot alpha particles (positively charged particles) at the gold foil. Most particles passed straight through the foil like the foil was not there. Some particles went straight back or were deflected (went in another direction) as if they had hit something. The experiment shows: Atoms are made of a small positive nucleus; positive nucleus repels (pushes away) positive alpha particles Atoms are mostly empty space 1. What is the charge of an alpha particle? Why is Rutherford's experiment called the gold foil experiment? 2.
