Lab: Half-Life

Question 1

Why are pennies good for simulating radioactive atoms? Check all that apply.

Revolt · Accepted Answer

Pennies have two sides—one to represent radioactive form and another to represent nonradioactive form.; You can easily see the two different forms.; You can create a large sample of pennies.; Pennies are not actually hazardous.; The chance of an atom decaying during a half-life cycle is 50%, the same as flipping a coin and getting tails.
