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.
The longest-lived radioactive isotope is 36 Cl, which has a half-life of 301,000 years. All other isotopes have half-lives under 1 hour, many less than one second. The shortest-lived are 29 Cl and 30 Cl, with half-lives less than 20 and 30 nanoseconds, respectivelyâthe half-life of 28 Cl is unknown. Standard atomic mass: 35.453(2) u.
