Review For the Final
This will help with Chemistry and if you get done, Earth Science
1) http://www.classzone.com/books/earth_science/terc/navigation/visualization.cfm
2) Scroll down to Chpt 5 and click on:
How Many Protons, Neutrons, and Electrons Are in Common Elements?
3) Step 1: Record an answer for the six pictures, then click on Step 2. Use your PT.
4) Step 2: Tell me how big a Cu (copper) atom is.
5) Write down what you know about subatomic particles (p,n,e) with regards to charge, location, and mass. Then, click Step 3 and move your cursor over the particles to check your answer. How did you do?
6) Try to build the first ten atoms of the PT and isotopes for each. Follow the directions in the box. Do you see a pattern?
a. What happens when electrons and protons are moved near each other?
b. What happens to the nucleus when it contains neutrons only? Protons only?
c. What happens when you try to put a third electron in the first energy level?
