What has a positive charge of electricity equal and opposite to the charge of the electron?

The proton is a subatomic particle found in the nucleus of an atom and carries a positive electric charge. This positive charge is equal in magnitude but opposite in sign to the negative charge carried by an electron. The existence of protons and electrons is fundamental to the structure of atoms, with electrons typically orbiting around the nucleus, which contains protons and neutrons.

Neutrons, on the other hand, are neutral particles with no charge, which is why they do not fit the criteria of having a charge equal and opposite to that of an electron. Ions are charged particles that can be either positive or negative due to the loss or gain of electrons, but they do not specifically refer to a particle with an equal and opposite charge to an electron like protons do. Lastly, electrons themselves carry a negative charge rather than a positive charge. The relationship between protons and electrons is a cornerstone in understanding atomic structure and the behavior of matter.
