List the first three parts to his theory.
1.)All matter is composed of extremely small particles called Atoms.
2.)Atoms of a given element are identical in size, mass, and other properties. Atoms that are from different elements differ.
3.)Atoms cannot be subdivided, created, or destroyed.
What happens when you use or test this particle hypothesis?
The paddle wheel between the two ends rolled toward the positive from the negative, in other words it started at the negative and rolled to the positive. When the paddle moved it showed the particles were able to push the paddle away from it. He then concluded the cathode rays were deflected from the negative side. He figured opposites attract so negative doesn't like a negative.
How did he discover the nucleus?
He discovered it by having a gold foil and then he shot alpha particles at it and some bounced off but only very rarely.
Did Democritus have a beard?
Indeed he had a beard.
Did Aristotle have a beard?
Yes, Aristotle had a beard and it was amazing.
List parts four and five.
4.)Atoms of different elements combine in simple whole number ratios to form chemical compounds. That means you cant have a fraction of an atom.
5.)In chemical reactions atoms are combined, separated, or rearranged.
What happens when you use a cathode ray tube?
(Visually)
The side near the positive end lights up.
