Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
The number of protons in the nucleus of an atom determines the element.
As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.
The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record.Below is a chart of commonly used radiometric isotopes, their half-lives, and the daughter isotopes they decay into.Let's say you found a fossil you think to be a human skeleton.One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.
