However, scientists can look at the decay of other elements in these objects allowing them to date them up to 2.2 billion years.

Carbon combines with other elements in complex ways to form the molecules that make up our bodies.

Most carbon on Earth is not radioactive, but a very small percentage is.

All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.

Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

When an atom varies in the number of neutrons, the variation is called an isotope. During radioactivity, the unstable isotope breaks down and changes into a different substance.
