which statements about radioactive decay are true? check all that apply. most elements are unstable. radioactive decay happens when one kind of atom becomes another kind. radioactive elements occur in nature. all elements have the same rate of decay. carbon - 14 decays into nitrogen - 14.

which statements about radioactive decay are true? check all that apply. most elements are unstable. radioactive decay happens when one kind of atom becomes another kind. radioactive elements occur in nature. all elements have the same rate of decay. carbon - 14 decays into nitrogen - 14.

Answer

Brief Explanations:

  • Most elements are stable, not unstable, so the first statement is false.
  • Radioactive decay is the process where one - kind of atom changes into another through the emission of particles or energy, so the second statement is true.
  • Radioactive elements such as uranium and radium occur in nature, so the third statement is true.
  • Different elements have different decay rates, so the fourth statement is false.
  • Carbon - 14 undergoes beta decay and decays into nitrogen - 14, so the fifth statement is true.

Answer:

  • Radioactive decay happens when one kind of atom becomes another kind.
  • Radioactive elements occur in nature.
  • Carbon - 14 decays into nitrogen - 14.
