Alpha particles produced by radioactive decay eventually
Chapter 20, Problem 103AP(choose chapter or problem)
Alpha particles produced by radioactive decay eventually pick up electrons from their surroundings to form helium atoms. Calculate the volume (in mL) of He collected at STP when 1.00 g of pure 226Ra is stored in a closed container for 125 years. (Assume that there are five a particles generated per 226Ra as it decays to 206Pb.)
