Matter was made up of solid material, which could be fashioned into tools
Chemists investigated the properties of only those materials that were of high value to humans
The effect of heat on copper, lead to the creation of a strong material (bronze) for use as tools
Iron combined with carbon to make steel, for even stronger tools
Everything was made out of Air - Water - Earth - Fire
Theory of Matter was based more on experimentation
Patricles can be compressed
System for the naming of chemicals was developed
Air is necessary for combustion to occur.
The time that we live in now
Observation principles during experimentation.
Raisin bun model with charged particles
Negatively charged particles orbiting around nucleus
Electrons rotate randomly around the nucleus.
