For this activity review the Content Slides on D2L (Atoms and Atomic Structure) and complete the activities/questions below.
Make a model of your three favorite elements on the Periodic Chart. The models must be 3-dimensional and be made out of common objects around your home. Place photos of your three models with descriptions on your blog. Your models must include the appropriate number and positioning of protons, neutrons and electrons.
1. What is the atomic number for each of your models?
2. What is the atomic mass number for each of your models?
3. In your models, which two subatomic particles are equal in number?
4. How would you make an isotope for one of your models? What would change with the model?
5. Considering the overall volume of your element models, what makes up most of the volume of an atom?
6. For one of your models, show with another image what happens when energy excites an electron.
7. Once the electron is excited, what do we typically observe when the electron returns to the ground-state?
8. Why are some elements different colors when they are excited?
9. With the Fourth of July coming up quickly, explain how the colors of fireworks arise.
10. Explain the overall organizational structure of the periodic table.
11. List two example elements for each of these groups or classes: Alkali Metals, Alkaline Earth, Halogens, Noble Gases, Transition Metals, Non-Metals, and Metalloids.
