- Is an electron: c. Beta particle
- Is pure energy: b. Gamma particle
Question 2
In the element above the mass number is ___ and the atomic number is ___ .**
- Blank 1: (Provide the mass number from the video)
- Blank 2: (Provide the atomic number from the video)
Question 3
Which process occurs when two nuclei come together to form one bigger nucleus?
- b. fusion
Question 4
Which process occurs when one nucleus splits to form two smaller nuclei?
- a. fission
Question 5
Scientists have been able to develop a nuclear fusion plant to generate energy.
- False (As of my training cut-off, fusion power plants are still experimental and not yet widely available.)
Question 6
Match the nuclear reaction to its description:
- Forms two lighter nucleus: a. Fission
- Forms one heavier nucleus: b. Fusion
- (Missing description provided as "cb794d20-2b7f-4bf4-a043-964706757c9a") (Need description)
- (Missing description provided as "808ecb1f-d7df-46f5-9d92-076db0dd74a0") (Need description)
- Has been successfully used to generate energy: b. Fusion (in experimental reactors, not yet for commercial use)
- Has NOT been successfully used to generate energy/electricity: a. Fission
Question 7
The missing box would be the number ___ and this is a form of ___ decay.
- Blank 1: (Provide the number from the video)
- Blank 2: (Provide the type of decay)
Question 8
The number in the box is ___ and this is a form of ___ decay.
- Blank 1: (Provide the number from the video)
- Blank 2: (Provide the type of decay)
Question 9
The number in the box is ___ and this is a form of ___ decay.
- Blank 1: (Provide the number from the video)
- Blank 2: (Provide the type of decay)
Question 10
The element in the missing box is ___ .
- Blank 1: (Provide the symbol from the periodic table)
Question 11
If the following element undergoes alpha decay, which element does it change into?
- c. Radium (Ra) (This depends on the element in question; Radium is a typical outcome of alpha decay but verify the specific element from the video.)
Question 12
A stable nucleus will decay, or emit, particles.
- False
Question 13
Match the particle to its description:
- Relatively large particle: c. Alpha particle
- This particle cannot penetrate very far into other materials: c. Alpha particle
- Can be absorbed by a sheet of paper: c. Alpha particle
- Can penetrate other materials moderately: b. Beta particle
- Can be absorbed by a sheet of aluminum: b. Beta particle
- Has no mass and a negative charge: b. Beta particle
- Has no mass and no charge: a. Gamma particle
- Can be absorbed by lead: a. Gamma particle
- Can travel long distances: a. Gamma particle
Question 14
The amount of time it takes for half of a sample to disappear is:
- c. half-life
Question 15
The half-life for a 100-gram sample of radioactive element X is 5 days. How much of element X remains after 10 days have passed?
- b. 25 g (After 10 days, two half-lives have passed, so 100g → 50g → 25g)
Question 16
Sodium-24 has a half-life of approximately 15 hours. If only one-eighth of the sodium-24 remains, about how much time has passed?
- a. 45 hours (Since one-eighth means three half-lives: 15h x 3 = 45h)
