*The narrator draws the pairs of electrons in the first energy ring right next to each other. This is different from what we discussed, but is also correct.
*The narrator also takes the mass number from the PT. The mass numbers you will use will be in the name of the element you are drawing. For example, Carbon-14 has a mass of 14 (even though this is different from what the periodic table says).

Answer the following questions. Complete sentences are not required. However, clearly number/organize your answers.
Review/Research
1. What is the region of the atom called that contains the electrons? (1 pt)
2. What is the region of the atom called that contains the protons and neutrons? (1 pt)
3. Which region of the atom contributes most of its mass? (1 pt)
4. Which region of the atom contributes most of its volume? (1 pt)
Simulation - Make sure that all boxes are opened and/or selected.
5. What determines the identity of an element: protons, neutrons, or electrons? (1 pt)
6. Build an atom that has an atomic number of at least 4 and a mass number of at least 8.
a. How many protons does this contain? Neutrons? What is the name of this element? (3 pts)
b. What is this element's mass number? (1 pt)
