Answer

Brief Explanations:

  1. Unstable atoms in radioactive substances do release particles through radioactive decay.
  2. Radioactive decay of an element follows a constant - rate process based on its half - life.
  3. A half - life is the time it takes for half of the original amount of a radioactive element to decay, not half of its lifetime.
  4. By definition, at one half - life, half of the original unstable element has decayed.
  5. Not all elements are radioactive; only certain isotopes of some elements are radioactive.

Answer:

Unstable atoms release particles. The radioactive decay of an element occurs at a constant rate. At one half - life, half of the original unstable element has decayed.
