What is the charge of a proton?

The charge of a proton is +1. Protons are subatomic particles found in the nucleus of an atom and are responsible for contributing positive charge to the atom. This positive charge is a fundamental property of protons, which distinguishes them from other subatomic particles such as neutrons, that carry no charge, and electrons, which carry a negative charge.

In the context of atomic structure, protons play a critical role in defining the identity of an element. The number of protons in an atom determines its atomic number and influences its chemical properties. Therefore, understanding that the charge of a proton is +1 is essential for grasping the basic concepts of atomic structure and chemistry.
