Radioactive decay is an important process that helps keep elements stable.

This happens when unstable parts of an atom, called nuclei, lose energy by giving off radiation. As a result, they change into more stable forms.

Here are the main points:

1. Types of Decay:

   • Alpha Decay: This is when an atom loses 2 protons and 2 neutrons. An example of this is Uranium-238.
   • Beta Decay: In this type, a neutron changes into a proton and releases an electron. A good example is Carbon-14 turning into Nitrogen-14.

2. Half-Life:

   • The half-life is the time it takes for half of a sample to decay. For instance, Carbon-14 has a half-life of about 5,730 years. This makes it useful for dating old organic materials.

3. Stability Influence:

   • Elements that have too many protons or neutrons are not stable. Radioactive decay helps these elements become stable. This process is really important for keeping a balance of different isotopes in our environment.
