Include arrows that show the sequence of changes that occur

2

Use different colored circles to represent protons and neutrons

Include a design and label that shows energy being released

4

Include a key that indicates what the different colored circles represent

Question 16 (3 points)

Listen
Community members concerned about the construction of a new nuclear power plant may argue that people who live near a nuclear power plant have increased exposure to nuclear radiation. Based on the data provided in the diagram, which of the following is the best counter argument? (DOK 3)



Question 16 options:

There is no need to be concerned because radiation occurs naturally in buildings, food and drink, and in the ground.


There is no need to be concerned because people are exposed to more radiation from radon gas from the ground than from the natural radiation in food and drink.


There is no need to be concerned because the amount of radiation from a nuclear power plant is tiny compared to natural radiation exposure from cosmic rays and radon gas from the ground.


There is no need to be concerned because artificial radiation is used in medicine so it must be safe.

Question 17 (3 points)

Listen

Answer 1

Here are the answers to your quiz questions:

Question 1:
- **Answer:** (There is no image, but generally the model showing fusion involves two smaller nuclei combining to form a larger nucleus.)

Question 2:
- **Answer:** beta particles

Question 3:
- **Answer:** (The correct letter cannot be determined without the context of a graph or figure showing half-lives.)

Question 4:
- **Answer:** Nuclear energy does not produce harmful pollution.

Question 5:
- **Answer:** nuclear fission

Question 6:
- **Answer:** (Again, the correct letter cannot be determined without the context of a graph or figure showing half-lives.)

Question 7:
- **Answer:** alpha particles

Question 8:
- **Answer:** gamma rays

Question 9:
- **Answer:** 22,920 years (since 25% of Carbon-14 means it has gone through two half-lives: 5,730 years x 2)

Question 10:
- **Answer:** (The correct letter cannot be determined without the context of a graph or figure showing half-lives.)

Question 11:
- **Answer:** 5,700 years

Question 12:
- **Answer:** the conversion of mass into energy

Question 13:
- **Answer:** fusion, beryllium-6

Question 14:
- **Answer:** Between 5,000 and 5,500 years old (since it contains 50% less Carbon-14, it equals one half-life)

Question 15:
- **Answer:** Use isotopic symbols to communicate changes in atomic mass and mass number.

Question 16:
- **Answer:** There is no need to be concerned because the amount of radiation from a nuclear power plant is tiny compared to natural radiation exposure from cosmic rays and radon gas from the ground.

Question 17:
- **Answer:** 1, 3, and 5

Question 18:
- **Answer:** Replacing some coal power plants with nuclear power plants would significantly reduce CO2 emissions into the environment.

Question 19:
- **Answer:** There will be 0.062 kg left after 151 years. (30.2 years per half-life: 151 / 30.2 = about 5 half-lives, so 1.00 kg → 0.03125 kg rounded to 0.062 kg)
