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

Helium is the second lightest element on Earth.

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

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

He is known as the alpha of the team.

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

We are in the same class.

He is thinking the same way.

He repeats the same routine every day.

We have the same hobbies.
