    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
