Which subatomic particle carries a positive charge?

The subatomic particle that carries a positive charge is the proton. Protons are found in the nucleus of an atom and are one of the primary building blocks of matter, along with neutrons and electrons. They have a charge of +1 elementary charge, which is essential in balancing the negative charge of electrons, allowing atoms to maintain electrical neutrality.

In contrast, neutrons are neutral, which means they have no charge and help stabilize the nucleus by adding mass without affecting the electrical properties. Electrons, on the other hand, hold a negative charge, which influences chemical bonding and reactions due to their interactions with protons and other electrons. Quarks are the fundamental constituents of protons and neutrons, and they can carry various charges, including positive and negative, but they do not represent an independent subatomic particle like protons do. Therefore, the proton stands out as the subatomic particle with a distinct positive charge.
