Different isotopes, which are versions of elements, behave in different ways when they decay, or break down. This happens because each isotope has a unique atomic structure. Some isotopes are unstable, meaning they change in ways that can be tricky to understand.

Here are the main types of radioactive decay:

1. Alpha Decay:

   • This type releases alpha particles, which are made of two protons and two neutrons.
   • It usually happens in heavy atoms. When this occurs, the atom loses some mass and changes into a different element.

2. Beta Decay:

   • In this process, a neutron changes into a proton, or a proton changes into a neutron. This change releases a beta particle.
   • It often happens in isotopes where the number of neutrons and protons is not balanced. Because of this, it can be hard to predict what will happen.

3. Gamma Radiation:

   • This involves high-energy rays that come from the nucleus of an atom when it is excited.
   • Gamma radiation usually occurs along with alpha and beta decay, making the whole process more complicated.

Studying these types of decay can be tough because it involves understanding complex topics in nuclear science. But with thorough studying, hands-on experiments, and helpful resources, students can get a better grasp of radioactivity and what it means in the real world.
