An alpha particle is the same as the nucleus of a helium atom.

Helium is the second lightest element on Earth.

Alpha rays are a type of particle emitted from radioactive materials.

The study of the atomic nucleus is an important field in physics.

He is known as the alpha of the team.

In this experiment, we will investigate the structure of atoms using alpha rays.
