Summarize: In general, how can you determine the mass number of the daughter product after alpha decay has taken place? Most of the helium used to fill balloons and blimps must be extracted from Earth’s crust. Activity B: Beta decay Get the Gizmo ready: • Click Reset, and turn off Show equation. For the simulated substance, every 10 seconds represents one half-life. Real radioactive samples will contain billions of radioactive atoms. Use the probe to measure how long it takes for exactly one-half of the original radioactive atoms to decay. On the next row, predict the number of radioactive atoms that will be present at each time. Half-life 0 1 2 3 4 5 Time (seconds) Predicted # radioactive atoms Actual # radioactive atoms 4.
