What is the charge of a proton?

The charge of a proton is +1. This positive charge is a fundamental property of protons and is crucial in understanding atomic structure. Protons are located in the nucleus of an atom and contribute to the atom's overall charge. The positive charge of protons balances the negative charge of electrons, which are found in the electron cloud surrounding the nucleus. This balance is what makes an atom electrically neutral when it has an equal number of protons and electrons.

In the context of basic atomic theory, neutrons, which are also found in the nucleus, carry no charge (0), and electrons carry a negative charge (-1). The concept of atomic charge involves understanding these particles and their roles in forming atoms and, subsequently, matter.
