What charge do protons possess?

Protons possess a positive charge, which is a fundamental property of these subatomic particles. In the context of atomic structure, protons are found in the nucleus of an atom alongside neutrons, which have no charge. The positive charge of protons plays a crucial role in determining the chemical properties of an element, as well as the overall charge of the atom when combined with electrons, which have a negative charge. The balance between the number of protons and electrons in an atom is what keeps it electrically neutral. When discussing the behavior of atoms in a refrigeration context, understanding the charge of protons helps to explain how atoms interact with each other, forming bonds that are essential for substances involved in refrigerants and HVAC systems.
