Provide examples of how your powers affect the world, environment, animals, or other people in a larger world view.

You have been learning about nuclear chemistry in class. Using your knowledge about nuclear chemistry, you will create a superhero with powers that were acquired due to exposure to nuclear material. This is an individual project; academic dishonesty will result in all the consequences specified in the student honor code. Your project is DUE: THURSDAY, OCTOBER 6TH. You may earn UP TO 10 points in the major grade category for the 1st 9-week grading period. This must be turned in on Google Classroom and will be subject to a PLAGIARISM check.

10 points – Write a SUPERHERO story that contains the following items.
Location – 1 point
Where did the exposure to nuclear material take place?
Radioactive Decay Equation – 2 points
Choose 2 types of radioactive decay (alpha, beta, or gamma) that caused your transformation into a superhero.
Show both (2) equations for the radioactive decay you chose above.
Powers – 1 point
State the power or powers acquired. Must be original powers…. things we have not seen in already existing superheroes!
Fission vs. Fusion – 1 point
Do your powers come from a fission or fusion reaction?
Show the fission or fusion equation that causes your powers.
How Powers Affect World – 1 point
Provide examples of how your powers affect the world, environment, animals, or other people in a larger world view.
Half-life (conclusion) – 2 points

C) sf4

1. Draw the correct Lewis Structures for each molecule on the list below and name each molecule following the rules for naming. You can print and fill this table to complete the answers for this question or you can copy the table in a piece of paper and fill in your answers. Make sure to also include in your paper: the total number of valence electrons for each molecule, how many bonds and lone pairs (non bonding) are around the central atom. Once you have completed the Lewis structures and the name of the four molecules, you can take a picture of your work and submit as the answer for this question. You can see an example here.
A) CH4
B) NH3
C) SF4
D) PCl3
2.Shape of a Molecule
To answer this question, you can refer to the Electron and Molecular Geometry Chart.
Use the Lewis structures from question 1 to predict the shape of the four molecules listed below
A) CH4
B) NH3
C) SF4
D) PCl3
Add the electron geometry and the molecular geometry to the paper containing your Lewis structures (question 1). Take pictures (combine them in one file if you have more than one picture) and submit as the answer for this question.You can see an example here.

3. To answer this question, you will need: toothpicks and play doh (at least two different colors) to create the molecular models. Start by creating small balls (about half an inch each one) of play doh of at least two different colors.
Using toothpicks for bonds, one tenth (1/10) of a toothpick for lone pairs and the play doh, create the molecular models of the following compounds:
A) CH4
B) NH3
C) SF4
D) PCl3
Your molecular models need to show the central atom with any lone pairs present on the structure and the bonds connecting the terminal atoms to the central atom. You don’t need to show the lone pairs on terminal atoms. Your models need to reflect the correct molecular geometry for the molecule. You can look at this presentation to guide you on how far or close should the bonds/lone pairs be.
Take pictures of your structures and submit all of them in the same file as the answer for this question. You can find an example here.


Use these questions as subheadings followed by your answers.

Post an example of a reaction and describe what type it is and why.

The web resource Types of Chemical Reactions (link in prompt attachment) from last week’s module gave a graphical descriiption of the different types of reactions explored to this point. Think about the compound that you chose for Milestone One. Which of the five different types of reactions is your compound involved in? Include information about heats of reaction and comment on whether the reaction is endothermic or exothermic and how the magnitude of this energy change compares with other reactions. Post an example of a reaction and describe what type it is and why.
Chosen compound: Xanthan Gum
