Specially equipped laboratories can do this with accuracy and precision.

So, in general, few people quarrel with the resulting chemical analyses.

Each atom is thought to be made up of three basic parts.

The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).

This process of changing one element (designated as the parent isotope) into another element (referred to as the daughter isotope) is called radioactive decay.

The parent isotopes that decay are called radioisotopes.

Orbiting around the nucleus are electrons (tiny particles each with a single negative electric charge).

The atoms of each element may vary slightly in the numbers of neutrons within their nuclei.

It is the interpretation of these chemical analyses that raises potential problems.
