  1. 3. The combining of two or more nuclei to produce one nuclei with the release of energy.
  2. 5. The forming of a new element artificially.
  3. 6. The particles that occupy the nucleus of an atom. You can find the number of these particles by adding up the protons and the neutrons.
  4. 9. Also known as radionuclides or radioactive nuclides and have unstable nuclei that make excess energy dissipate by spontaneously releasing radiation.

  1. 1. The changing of an element into another form through radioactive decay.
  2. 2. A notation that shows the chemical symbol, the mass number, and the atomic number of the isotope.
  3. 3. When an unstable, radioactive element decays into a series of other elements until a stable element is formed.
  4. 4. When heavy nuclei are bombarded with neutrons and split with the release of energy.
  5. 7. Two or more forms of the same element that have the same number of protons but different number of neutrons in their nuclei. They differ in atomic mass but have the same chemical properties.
  6. 8. The time it takes for half the quantity of a radioactive sample to decay.
