Two containers hold the same radioactive isotope. container a contains 1000 atoms, and container b contains 500 atoms. which of the following statements about containers a and b is true? two containers hold the same radioactive isotope. container a contains 1000 atoms, and container b contains 500 atoms. which of the following statements about containers a and b is true? the rate of decay of atoms (half-life) in container a is greater (or longer) than the rate of decay of atoms (half-life) in container b. the rate of decay of atoms (half-life) in container b is greater (or longer) than the rate of decay of atoms (half-life) in container a. the rate of decay of atoms (half-life) in container b is the same as the rate of decay of atoms (half-life) in container a.
