- 2. Pudding & Clouds ChemCatalyst In the 5 th century BCE, a Greek philosopher named Leucippus and his student, Democritus, stated: “ All matter is made up of particles that cannot be divided. These particles are called atoms.” What do you think atoms are?
- 3. Pudding & Clouds Atoms extremely small particles, cannot be seen, even with microscopes from the Greek word for indivisible often called smallest unit of matter scientists use models supported by scientific evidence to describe atoms
- 6. Pudding & Clouds Parts of an Atom Mostly empty space Dense nucleus of protons and neutrons Electrons around nucleus Bohr Model is mostly commonly used
- 7. Pudding & Clouds Wrap-Up All matter is made up of extremely small particles called atoms. These particles are too small to be seen even with a microscope. Science is theoretical and dynamic. Models and theories are continually being revised, refined, or replaced with new models and theories.
