If the symbol for this isotope is Am, which of the following correctly describes its subatomic ... WebThe half-life of Radium-226 is 1600 years. This means a 1 kg radioactive sample today would decay to a 1/2 kg radioactive sample after 1600 years. Analyze the table along with the animation to identify the pattern and relationship between number of half-lives, kilograms of radioactive sample size, nonradioactive sample size, and percent decayed.
