  1. 2. an uncharged atomic particle that has a mass nearly equal to that of the proton
  2. 4. They have the same atomic number and position in the periodic table, but differ in nucleon numbers due to different numbers of neutrons in their nuclei
  3. 5. Unlike alpha and beta particles, which have both energy and mass, theese rays are pure energy.
  4. 8. a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of decay
  5. 9. composite particles consisting of two protons and two neutrons tightly bound together
  6. 10. a reaction in which the nucleus of an atom splits into two or more smaller nuclei
  7. 11. a sequence of reactions where a reactive product or by-product causes additional reactions to take place.
  8. 12. a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions
  9. 13. a positive electric charge ts mass is slightly less than that of a neutron
Down
  1. 1. nuclei that are unstable and that decay by emitting energetic particles
  2. 3. the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.
  3. 6. the total number of protons and neutrons in a nucleus.
  4. 7. the amount of time it takes to decay half of an element
  5. 9. the number of protons in the nucleus of an atom
