and Ions Jim Geiger Cem 151 Atomic Theory of Matter The theory of atoms Original to the Greeks Leuccipus Democritus and Lucretius Aristotle thought they were nuts He believed that one could divide up a piece of matter an infinite number of times that is one never came up with a piece of matter that could not be further divided He suggested that everything in the world was made up of some combination of four elements earth fire water and air The elements were acted upon by the two forces of gravity and levity Gravity was the tendency for earth and water to sink and levity the tendency for air and fire to rise.

For Example: If you have a piece of gold and cut it into smaller and . smaller pieces, . you would eventually reach a point where you couldn’t cut the gold up any smaller. That smallest piece would be an atom of gold.. In . a chemical equation, like the one below, you will notice that there are regular-sized numbers in front of some of the molecules and small numbers after certain atoms within a molecule. . The little number is called the . What are Atoms?. Atoms. are the building blocks of matter made up of Protons, Neutrons & Electrons.. Inside the Atom.
