Write a hypothesis about how the number of half-lives affects the number of radioactive atoms. use the "if . . then . . because . ." format and be sure to answer the lesson question: "how does the number of radioactive atoms change over time? "
answer- if the number of half-lives increases, then the number of radioactive atoms decreases, because approximately half of the atoms' nuclei decay with each half-life.
