  1. 3. decay a change in the nucleus of an atom
  2. 4. negative radiation radioactive decay of an atom resulting in the atomic number of the atom increasing by one and the mass number remaining the same
  3. 6. radiation A high-energy electromagnetic emission caused by radioactive decay
  4. 7. an isotope that is unstable and undergoes radioactive decay
  5. 8. particle product of the radioactive decay of a nucleus; consists of two proton and two neutrons and carries a 2+ charge

  1. 1. decay the process by which radioisotopes decay and emit radiation
  2. 2. positive radiation radioactive decay of an atom resulting in the atomic number of the atom decreasing by one and the mass number remaining the same
  3. 3. the process by which radioisotopes decay and emit radiation
  4. 5. radiation decay of an unstable nucleus with the loss of an alpha particle resulting in the mass number of the atom decreasing by four and the atomic number of the atom decreasing by two
  5. 7. the process of emission of energetic particles or energetic waves
