Section 1:
Match the following people with their accomplishments:
A. Dalton
B. Thomson
C. Rutherford
1. Discovered the electron
2. Discovered the nucleus
3. His model of the atom is often referred to as the “plum pudding” model.
4. First stated that atoms of different elements have different masses.
5. His model of the atom is often called the “planetary” model

My indoor Olympic swimming pool (2500KL) developed a leak while I was vacationing on my yacht off of the
coast of Marseille, France this summer. Upon my return home, I discovered, to my dismay, that my pool
was completely drained. If my hose delivers water (Evian –of course!) at a rate of 5 gallons/min, how many
days will it take to refill my pool?
