Carbon- when paper burns it creates carbon
Copper- We find copper in our everyday lives in pennies
Aluminum- We find in pop cans and of course aluminum foil
1. What is the atomic number for each of your models?
a. Carbon- 6
b. Copper-29
c. Aluminum-13
2. What is the atomic mass number for each of your models?
a. Carbon- 12.0107
b. Copper-63.546
c. Aluminum-26.981538
3. In your models, which two subatomic particles are equal in number?
a. Non are
4. How would you make an isotope for one of your models? What would change with the model?
a. Isotopes are variants of atoms of a particular chemical element, which have differing numbers of neutrons.
5. Considering the overall volume of your element models, what makes up most of the volume of an atom?
a. It is mostly filled with nothing. There is a central heavy nucleus and “whizzing’ round it are a number of much lighter much smaller electrons. From the outermost reaches of the electrons orbits to the centre of the nucleus there is an awful of nothing in it.
6. 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?
a. The color emitted depends on the amount of energy released.
a. The colors of fireworks are determined by the minerals placed inside the shell along with the explosive charges - for example, strontium produces a red color. For the sparkling, they include aluminum shavings. See the links below and click through on some of the articles for more information.
9. With the Fourth of July coming up quickly, explain how the colors of fireworks arise.a. The colors of fireworks are determined by the minerals placed inside the shell along with the explosive charges - for example, strontium produces a red color. For the sparkling, they include aluminum shavings. See the links below and click through on some of the articles for more information.

10. Explain the overall organizational structure of the periodic table.
a. Elements are listed in order of increasing atomic number. Rows are arranged os that elements with similar properties fall into the same columns.
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.
- Alkaline Metals-Sodium
- Alkaline Earth- Magnesium
- Halogens- Chlorine
- Noble Gases- Neon
- Transition Metals- Iron
- Non Metals- Hydrogen
- Metalloids- Boron
