What are atoms like? ATOMIC THEORY • The idea that matter consists of small particles called atoms. • The atom is the smallest particle that makes up matter and can not be further broken down. • Atomic models of matter have existed for thousands of years, but the generally accepted model by John Dalton was not published until 1809. PROPERTY • A property is: PROBLEM STATEMENTS • 1. What evidence do we have for the existence of atoms? • 2. What are atoms like? ATOMS IN A LIQUID • Atoms in a liquid can • move and are spread out. Atoms are loosely arranged ATOMS IN A SOLID • In a solid , atoms are arranged very neatly and densely. ATOMS IN A GAS • Atoms in a gas move • quickly Atoms in gases are not neatly arranged in rows, they are very spread out WHAT YOU WILL DO! • 1. Cycle through 7 • • • different lab stations 2. Write down the problem stated 3. Record your descriptions and observations. 4. Make sketches
