1. What is the atomic number for each of your models?see above
2. What is the atomic mass number for each of your models?see above
3. In your models, which two subatomic particles are equal in number? Electrions and Protons
4. How would you make an isotope for one of your models?  What would change with the model?This just means that you add or take away a neutron. It is still the same element, but there is just a different amount of neutrons. The amount of protons and electrons stays the same.
5. Considering the overall volume of your element models, what makes up most of the volume of an atom?Electrons take up most of the volume of an atom. On the other hand, the protons and neutrons are what makes up the mass of the element model.
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?
 We observe light
8. Why are some elements different colors when they are excited?
Lithium gives off red flames and sodium gives off a yellow flame. 
9. Do a little research to list which elements are used to make the different colors of fireworks.
Aluminum: Silver Fireworks
Copper Salts: Blue Fireworks
Sodium Compounds: Yellow Fireworks
Barium Compounds: Green Fireworks 

Stronium Compounds: Red Fireworks

Antimony: Glitter effects in the fireworks

Calcium Salts: Orange Fireworks

10.  Explain the overall organizational structure of the periodic table.
The periodic table is organized based on Atomic Structure. This is done so by adding protons and electrons. They then are organized on the table in rows or periods based on their outer shell number.Then, they are organized into columns based on the number of electrons in their outer shell. The elements for each of the classes (alkali metals, alkaline earth, halogens, noble gases, transition metals, non-metals, and metalloids) are then grouped together.
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.
Alkali Metals: Lithium and Sodium
Alkaline Earth: Magnesium and Calcium
Halogens:Flourine and Cholorine

Noble Gases: Neon and Helium

Transition Metals: Titanium and Iron

Non-Metals:Hydrogen and Carbon

Metalloids: Boron and Silicon
