The rate of. decay is a fixed rate called a half-life. The half-life of a radioactive isotope refers to the amount of time. required for half of a quantity of a radioactive isotope to decay. Carbon-14 has a half-life of 5,730 years, which means that if. you take one gram of carbon-14, half of it will decay in 5,730. years. Different isotopes have different half-lives.
After 30 days, 5.0 grams of a radioactive isotope remains from an original 40.-gram sample. What is the half-life of this element?1) 5 days 3) 15 days2) 10 days 4) 20 days54.
