Answer:

A radioactive element emits alpha, beta and gamma particles under spontaneous nucleus degeneration.

So the above statements describe the radioactive elements.

  1. have a consistent number of particles
  2. have a half-life that determines their rate of decay
  3. release energy and particles to maintain radioactivity  

While the other options do not go with radioactive elements as not all the elements occur in nature and decay rate may not be consistent.

Phrases that describe radioactive elements are- occur in nature, have constant decay rate, have constant number of particles (alpha, beta, gamma), have half-life that determines their rate of decay.

Explanation:

  • Radioactive elements is the elements that undergoes radioactive decay with the emission of alpha, beta or gamma rays.
  • Element is called radioactive because electrons or the particles radiates from center.
  • Radium, Thorium, Uranium are some examples of radioactive elements.
  • Radioactive decay law states that decay rate is constant and independent of time.
