Atoms are made of three basic subatomic particles: protons, neutrons, and electrons. Each of these particles has a different electric charge. Protons have a positive charge (+), electrons have a negative charge (−), and neutrons have no charge—they are neutral.

Protons are found in the nucleus, which is the center of an atom. Their positive charge helps balance the negative charge of electrons that move around the nucleus. This balance is what keeps an atom stable.

Protons also play another important role: they help define what element an atom is. For example, if an atom has one proton, it’s hydrogen. If it has six protons, it’s carbon. So, the number of protons is like the ID number of an element.

Electrons are found outside the nucleus and are much smaller. Neutrons also stay inside the nucleus but do not carry any charge.

So, the particle with a positive electric charge is the proton. Knowing this helps in understanding electricity, chemistry, and the basics of atomic science.
