DIRECTIONS


Play around with the protons, neutrons, and electrons for about 2 minutes
Then start building and drawing the following atoms. Call Mrs. Schwendemann over to quiz you and your partner when you complete each question. If she is busy quizzing other sections you can move on until she can get to you.
 COLOR CODE with highlighters please!!!
Hydrogen
Now create a neutral, stable hydrogen atom and draw it in the box to your right (in the “orbit” model).
Group Quiz Questions:
1) Where do protons go? Neutrons go? Electrons go?
2) How many protons does hydrogen have? Electrons?
3) What happens if you add/subtract electrons?
4) What happens if you add/subtract protons?
5) What happens if you add/subtract neutrons
6) What’s the net charge for a neutral hydgroen atom?

Helium
Now create a neutral, stable helium atom and draw it in the box to your right (in the “cloud” model).
Group Quiz Questions:
1) Where do protons go? Neutrons go? Electrons go?
2) How many protons does hydrogen have? Electrons?
3) What happens if you add/subtract electrons?
4) What happens if you add/subtract protons?
5) What happens if you add/subtract neutrons
6) How is the cloud mode different from the orbit model?

Carbon
Now create 2 neutral, stable carbon atoms and draw it in the boxes to your right (in the “orbit” mode).
Group Quiz Questions:
1) How many protons, neutrons, and electrons does each have?
2) What are 2 different versions of the same type of atoms called?
3) Which one is the “right” one, the
“normal” looking carbon atom? How would you know?

Games
 Click on the Games tab in the top left corner.
 Play each level of game.
 When you finish each game, a score screen appears. When you’re 8 out of 10 or greater show
Mrs. Schwendemann so he can sign your paper. If you don’t get 8 out of 10 or greater, keep playing until you get it! Don’t’ write your score or time down until you’re ready to be signed!
