radioactivity dating to materials-29

nucleus,in physics, the extremely dense central core of an atom.

The Nature of the Nucleus Composition Atomic nuclei are composed of two types of particles, protons and neutrons, which are collectively known as nucleons......

A decay, also known as a disintegration of a radioactive nuclide, entails a change from an unstable combination of neutrons and protons in the nucleus to a stable (or more stable) combination. Radioactive atoms decay principally by alpha decay, negative beta emission, positron emission, and electron capture.

The type of decay determines whether the ratio of neutrons to protons will increase or decrease to reach a more stable configuration. How does the neutron-to-proton number change for each of these decay types?

Some of the intermediate stages include the heavier elements thorium, radium, radon, and polonium.
