Description
Radioactivity
Radioactivity is a natural process where certain atoms release energy from their nuclei. This release occurs when atoms are unstable, meaning their nucleus has too many particles or an incorrect balance of particles. As the atoms break down, they give off particles or rays that we ...

Imagine the nucleus—the tiny core of an atom. Sometimes, this core is unstable. It may have the wrong balance of protons and neutrons or hold too much energy.
When this happens, the nucleus tries to find balance by giving off energy and tiny particles. This natural process is called radioactivity.
One example is uranium, ...
