What happens to the mass of a sample containing a radioactive element during its half-life?

A. The mass decreases by half.

B. The amount of mass is doubled.

C. Eventually there is no mass at all.

D. The mass remains the same.

  • Science -

    Of course, the mass remains the same for practical purposes. During the release of energy, a very tiny portion of mass is converted to energy, but that mass is extremelyl small, and cannot be determined by ordinary means.
