1. It is best to post one question at a time.
2. We shall be happy to critique your thoughts. These points are discussed in detail in most texts. We don't do homework be we are happy to help you do it.
3. Any specific questions you have about understanding any of the above (or anything else) we shall be happy to help.
1.How does the mass of a nucleon compare with the mass of an electron?
2.Distinguish between atomic number and atomic mass number.
3.Why do protons in a very large nucleus have a greater chance of flying apart by electrical repulsion?
4.What exactly is transmutation?
5.Describe alpha, beta, and gamma rays. What exactly is each ray composed of? What are their characteristic radiation characteristics?

Most of the questions you asked can be answered with a dictionary or any of the sources that a search engine would come up with. I recommend that you get the answers that way, because it will make you think about and remember the answers better.
Question #3 requires more thought and a deeper understanding of nuclear physics. As nuclei get larger, the energy needed to hold all of the protons together against the long-range Coulomb repulsion forece increases with the square of the atomic number. The short-range "strong force" between nucleons, which hold the nucleus together, increases in proption to the atomic mass umber and cannot hold the nucleus together when it becomes too large
