Which particle is positively charged within an atom?

The proton is the positively charged particle within an atom. Each atom consists of three primary subatomic particles: protons, neutrons, and electrons. Protons have a positive charge, while electrons carry a negative charge, and neutrons are neutral with no charge. The positive charge of protons is crucial for the structure of the atom, as it contributes to the atom's overall charge balance and its interactions with other atoms.

In a neutral atom, the number of protons equals the number of electrons, which balances the charge. The presence of protons in the nucleus defines the atomic number of an element, determining its identity on the periodic table. Understanding the role of protons is fundamental in learning about atomic structure, chemical behavior, and the principles of electricity and magnetism in the field of electrical work.
