A non-radioactive element is an element that has at least 1 isotope that is not radioactive. The means that at least one isotope has a stable nucleus that does not break down by shooting off high-energy particles.
Iodine is a nonradioactive halogen that occurs as a solid at room temperature and pressure.
hydrogen-1hydrogen-2carbon-12etc.
Lead 206 (Pb)
This phenomenon is not mandatory.
You can use relative dating which is looking at the rocks around it, or you can use radiometric dating, which compares the amount of radioactive element with the amount of nonradioactive element in the rock.
Iodine is a nonradioactive halogen that occurs as a solid at room temperature and pressure.
hydrogen-1hydrogen-2carbon-12etc.
nonradioactive
No, americium is an unstable and radioactive chemical element.
Lead, the isotope Pb 206.
This is impossible.
Lead 206 (Pb)
This phenomenon is not mandatory.
Redioactive element
The ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) is measured.
This is a radioactive chemical element.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
