introduction to half - lives link to half - life investigation simulation 6. go to the above simulation page and decay element x through 4 half - lives. record your observations in the table below: half lives, # of undecayed particles, observations about the graph: 0, 1000; 1, 500; 2, 250; 3, 125; 4, 63 7. go to the above simulation page and decay element y through 4 half - lives. record your observations in the table below: half lives, # of undecayed particles, observations about the graph: 0, 1000; 1, 500; 2, 250; 3, 125; 4, 63 8. based on what you observed in the simulation describe what a half - life is.
Answer
Brief Explanations:
A half - life is the time it takes for half of the atoms of a radioactive substance to decay. In the simulation, starting with 1000 undecayed particles, after 1 half - life, 500 remain (half of 1000), after 2 half - lives 250 remain (half of 500), after 3 half - lives 125 remain (half of 250) and after 4 half - lives 63 (approximately half of 125) remain. The graph shows an exponential decay pattern where the number of undecayed particles decreases rapidly at first and then more slowly over time.
Answer:
A half - life is the time interval during which the number of undecayed particles of a radioactive substance reduces to half of its initial amount, and the decay follows an exponential pattern as seen in the graph.
