Fun-Fact for the Nickel: The nickel’s name is unique.... It's the only U.S. coin that is called by its metal content—even though the metal alloy in a nickel is only 25 percent nickel. The rest is copper. The isotope nickel-63 has a half-life of 100 years. If a tested sample has five grams of nickel-63 and is estimated to be 400 years old, how many grams of nickel-63 were initially in the sample?
