Compare Single Parent During natural radioactive decay, not all atoms of an element are instantaneously changed to atoms of another element. The decay process takes time and there is value in being able to express the rate at which a process occurs. Our own bodies contain kilograms of carbon, and it is intriguing to think there are hundreds of 14 C decays per second taking place in us. Related Simulations. Very old biological materials contain no 14 C at all. Figure 3. If a researcher isolates 1. Check Your Learning More accurate dates of the reigns of ancient Egyptian pharaohs have been determined recently using plants that were preserved in their tombs.

In the Classroom Unstable nuclei decay. However, some nuclides decay faster than others. For example, radium and polonium, discovered by Consolidating superannuation atomic mass Curies, decay faster than uranium. This means they have shorter lifetimes, producing a greater rate of decay. In this section we explore half-life and activity, the quantitative terms for lifetime and rate of decay. How to find someone on hookup website The spontaneous change of an unstable nuclide into another is radioactive decay. The unstable nuclide is called the parent nuclide ; the nuclide that results from the decay is known as the daughter nuclide. The daughter nuclide may be stable, or it may decay itself.
