Answer – The charge of a proton is coulombs.
Explanation:
The nucleus contains two types of subatomic particles – protons and neutrons. While neutrons possess no charge, protons have a positive charge that is balanced by the electrons outside the nucleus. In other words, protons and electrons have equal but opposite charges so that the atom remains electrically neutral.
The charge of an electron is coulombs. Therefore, the equal but opposite charge of a proton is coulombs. It is alternatively indicated by , where e stands for elementary charge.
