Answer the following questions with at least 100 words per question.
1. What are the two principal differences between nuclear reactions and ordinary chemical changes?
2. How does nuclear fission differ from nuclear fusion? Why are both of these processes exothermic?
3. What is the band of stability and why is it important?
4. Write a brief description or definition of three or four of each of the following (after about 5 posts - other students elaborate on one of the points a-h):a. Nucleonb. α particlec. β particled. Positrone. g rayf. Nuclideg. Mass numberh. Atomic number
5. Many nuclides with atomic numbers greater than 83 decay by processes such as electron emission. Explain the observation that the emissions from these unstable nuclides also normally include α particles. Why is electron capture accompanied by the emission of an X-ray?

This assignment had a set of questions on nuclear reactions like nuclear fission and nuclear fusion reactions and differences between these reactions and normal chemical reactions. It also asked about the description of nucleon, atomic number, positron, mass number etc.It asked about band stability and its significance as well.
Thank you for your proceeded with help on this task. If it's not too much trouble thank the expert abundantly to take this on so a minute ago. A debt of gratitude is in order for running an awesome written work service.
