Nuclear Physics

1. Albert Einstein's mass energy equation
4. very weak only noticeable when large masses are involved
7. pretty strong but only operates over short distances. Responsible for radioactive decay
9. charged particles and energy that are emitted from the nuclei of radioisotopes
13. the process in which an unstable atomic nucleus emits charged particles and energy
14. an electron emitted by an unstable nucleus
15. the splitting of an atomic nucleus into two smaller parts
16. the time required for one half of a sample of a radioactive element to decay

2. in it, neutrons are released during the splitting of an initial nucleus trigger a series of nuclear forces
3. a positively charged particle made up of two protons and two electrons-same as a helium nucleus
5. responsible for electrostatic attraction and repulsion
6. the attractive force that binds protons and neutrons together in the nucleus
8. the conversion of atoms of one element to atoms of another-involves nuclear but not chemical change
10. where the nuclei of two atoms combine to form a larger nucleus
11. slows a nuclear chain reaction by absorbing neutrons
12. nuclear radiation that occurs naturally in the environment
