Title: Radon has a 4-day half-life. Starting with 10 radon atoms, how many will remain Post by: einsteindude on Dec 3, 2014 Radon has a 4-day half-life. Starting with 10 radon atoms, how many will remain after 4 days?
A) Precisely zero. B) About 5, but this prediction is uncertain due to the inaccuracies of our measuring devices. C) Precisely five. D) About 5, but this prediction is uncertain due to quantum uncertainties. E) Either four, or five, or six. Title: Re: Radon has a 4-day half-life.
