Here's why:

* Protons: Positively charged particles located in the nucleus of an atom.

* Electrons: Negatively charged particles that orbit the nucleus.

* Neutrons: Neutral particles located in the nucleus.

When an atom has an equal number of protons and electrons, it is considered electrically neutral. If an atom loses electrons, it becomes positively charged because it has more protons than electrons. This is called a cation.
