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 components that define the atom's identity. The number of protons determines the atomic number of an element, which in turn identifies the element itself. For example, hydrogen has one proton, while carbon has six protons.

In addition to their positive charge, protons play a crucial role in the atom's overall stability and in the balance of electrical charges within the atom. This is in contrast to neutrons, which carry no charge and are neutral, and electrons, which carry a negative charge. The nucleus refers to the central part of the atom that contains protons and neutrons but does not carry a charge itself, as it is the sum of these particles.

Understanding the charge of protons is important for grasping concepts related to atomic structure, bonding, and electrical forces, all fundamental areas of study in electricity and electronics.
