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.

B

Explanation:

This is due to the differences in the concentrations of the radioactive isotopes in the two containers of the same volume. In container A, with a higher density of atoms, there is a higher chance of a neutron released in the decay of one atom, hitting another atom and splitting it. This is in comparison to container B that has fewer atoms that are widely dispersed due to the lower density. Atoms in cointainer A will therefore decay faster (shorter half-life) than atoms in container B.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
