For each radioactive decay process described:
1. The most likely process for polonium to become stable is alpha decay.
2. Alpha decay generates kinetic energy.
3. The radioactive decay process represented by the equation 14 6C → 14 7N + 0 -1e is beta-minus decay.
4. In beta-plus decay, the nucleus changes by having the mass number remain the same, and the atomic number decreases by one.
5. In gamma decay, the nucleus becomes more stable by repositioning its particles.
To answer the question "The rest of the assignment:" and provide explanations for each answer, here are the explanations for each question:
1. Polonium has a large, unstable nucleus. Through which process is it most likely to become stable?
Answer: alpha decay
Explanation: Polonium, being an element with a large and unstable nucleus, is most likely to become stable through alpha decay. In alpha decay, the nucleus emits an alpha particle which consists of two protons and two neutrons, effectively reducing the size and instability of the nucleus.
2. Which type of energy does alpha decay generate?
Answer: kinetic
Explanation: Alpha decay generates kinetic energy. When an alpha particle is emitted from the nucleus, it possesses a certain amount of kinetic energy due to the high speed at which it is expelled.
3. Use the equation to answer the question.
14 6C → 14 7N + 0 −1e
Which type of radioactive decay does the equation model?
Answer: beta-minus decay
Explanation: The given equation represents beta-minus decay. It shows the decay of Carbon-14 into Nitrogen-7 while emitting a beta particle (consisting of an electron) from the nucleus.
4. How does the nucleus change in beta-plus decay?
Answer: The mass number remains the same, and the atomic number decreases by one.
Explanation: In beta-plus decay, the nucleus undergoes a transformation where a proton is converted into a neutron, resulting in the emission of a positron (a positively charged electron). This process leads to a decrease in the atomic number while maintaining the same mass number.
5. An unstable nucleus undergoes gamma decay. How does the nucleus change?
Answer: It becomes more stable by repositioning its particles.
Explanation: Gamma decay does not involve the emission of any particles. Instead, it occurs when the nucleus releases high-energy gamma rays (electromagnetic radiation) to achieve a more stable energy state. Therefore, the nucleus becomes more stable by repositioning its particles energetically without any change in its structure or composition.
I hope these explanations provide a clear understanding of the concepts behind the answers to the questions. If you have any further inquiries, feel free to ask!
