Protons are subatomic particles found in the nucleus of every atom, and they are positively charged, which distinguishes them from neutrons (which are neutral) and electrons (which are negatively charged). Protons, along with neutrons, make up the atomic nucleus, and the number of protons in an atom’s nucleus determines the atomic number and thus the element’s identity. For example, an atom with one proton is hydrogen, while an atom with six protons is carbon. The mass of a proton is approximately 1 atomic mass unit (amu), which is roughly equivalent to the mass of a neutron but about 1836 times the mass of an electron. Protons are stable particles, and in hydrogen, the simplest atom, the proton serves as the nucleus itself. The study of protons is crucial in the fields of chemistry, physics, and various applications including medical imaging and nuclear power.
