Topic 2 Question for 5 Points Performed experiments that determined there were smaller particles within an atom. He discovered that atoms contain negative charged particles (electrons) that were mixed evenly throughout the atom. His model was called the “Plum Pudding” model. Show Answer

Topic 2 Answer for 5 Points Thomson Back to Board

Topic 2 Question for 10 Points Proposed the existence of atoms. He said if you keep cutting a piece of matter in half, eventually you will end up with a tiny particle that cannot be cut or divided any further. This particle is called atomos, a Greek word meaning “not able to divide”. Show Answer

Topic 2 Answer for 10 Points Democritus Back to Board

Topic 2 Question for 15 Points All substances are made of small particles called atoms. These atoms were small, hard, dense spheres that could not be changed, created, or destroyed. All atoms of the same element are identical and different from atoms of other types of elements. Atoms cannot be divided into anything simpler. Show Answer
