A student claims that the equation models beta-minus decay because the atomic number of the nucleus decreases by one. In one or two sentences,
explain the error in the student's reasoning.
10/6 C -> 10/5 B + 0/+1 e
Radioactive Decay Energy
1. alpha decay
2. kinetic
3. beta-minus decay
4. The mass number remains the same, and the atomic number decreases by one.
5. It becomes more stable by repositioning its particles.
Alpha Particle Emission
1. nuclear fusion
2. two protons and two neutrons
3. The model shows alpha decay, which is a type of nuclear fission.
4. The model shows alpha decay, which is a type of nuclear fission.
5. Gamma emission is a type of radioactive decay, but it is not a fission reaction.
Nuclear Processes Practice
- People of all sorts, dogs, and minerals... if you don't just click answers then push "Check Answer," I don't know what you're doing. Don't waste your time... less that's your thing but uh... don't think it is.
Nuclear Processes Test
1. the total number of protons
2. The number of protons in the atom changes.
3. The spontaneous emission of radiation.
4. Mashing to marshmallows together.
5. There must be a way for unstable nuclei to become stable nuclei.
6. The nuclei combine in a fusion reaction.
7. The number of nucleons stays the same, while total mass decreases slightly.
7. The nucleus with the greatest positive charge is on the right side of the reaction.
8. A nucleus with a large mass will be on the left side, and there will be neutrons in the equation.
9. The number of nucleons stays the same, while the number of nuclei increases.
9. Atoms are split into smaller pieces during fission.
10. A neutral neutron strikes a large positive nucleus.
10. A neutral particle is striking a positive particle breaking into more neutral and positive particles
11. An unstable nucleus releases a particle containing two protons and two neutrons.
12. gamma decay
13. helium
14. After the ejection of an alpha particle, the remaining nucleus has a mass number that is four less and an atomic number that is two less, so alpha decay is a type of nuclear fission.
15. Beta decay releases a particle, while gamma decay only reduces the energy level. Neither beta decay nor gamma decay is a form of nuclear fission.
16. (paraphrase the Brainly answer) The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
17. (paraphrase me) Nuclear fusion is responsible and its enormous output of energy is provided by gravitational contraction. Google about the sun and paraphrase it. If you get bad marks on it, look at the teacher's notes and do corrections on it and paraphrase their words.
18. It is beta PLUS decay, emission of a POSITIVELY charged positron (like an electron but charge + not -. That means that the proton that emitted the positron becomes a neutron and with one less proton the atomic number decreases by one.
dw folks, I'll return with the semester
