D: 13 protons, 14 neutrons, 13 electrons

E: None of the above is the right answer

2. How many filled shells of electrons does Na (sodium ) have? *

Look at the numbers with the dashes below the element.

A: 3 filled shells

B: 2 filled shells

C: 1 filled shell

D: 4 filled shells

E: Tortous Shell

3. Which element has no reactivity due to having filled electron shells? *

A: Fluorine, F

B: Oxygen, O

C: Lithium, Li

D: Neon, Ne

Leo the Lion says, "GRRRRRRRR!!!"

A: Fe, Iron

B: P, Phosporus

C: N, Nitrogen

D: Cl, Chlorine

E: SOS

6. In the demo video posted, how are electrons being affected? *

A: electrons are being shared between the Na and Cl.

B: Electrons are being transferred from the Na to the Cl.

C: Electrons are being shared by the Na and the water.

D: Electrons are being transferred from Cl to the Na.

E: None of the above answers are correct.

7. When Oxygen gains or shares 2 more electrons it has the same filled shell and stability as what element? *

A: Ne, Neon

B: He, Helium

C: C, Carbon

D: Se, Selenium

E: No

8. How many electrons does Calcium +2 ION have? *

Ca = Calcium, I say atom you say, neutral!!! This is not a an atom!!!!!

A) 40 electrons

B) 20 electrons

C) 18 electrons

D) 19 eletrons

E) None of the above choices are correct.

9. Why was the demo reaction exergonic? *

A) Na and Cl become stable when they react (bond) thus energy is released.

B) Na and Cl become unstable when they react (bond) thus energy is absorbed.

C) Na and Cl become stable when they react (bond) thus energy is absorbed.

D) Na and Cl become unstable when they react (bond) thus energy is released.

10. Electrons in Cellular Respiration are shuttled to the Electron Transport System by NAD+ and FAD *

A: and electrons become less bound with Oxygen, becoming more reduced that originally in glucose.

B: and electrons become more bound with Oxygen, becoming more oxidized than originally in glucose.

C: and these electrons are slowly given energy by ATP

D: to the outside the mitochondria.
