  1. Proton - Wikipedia

    • A proton is a stable subatomic particle, symbol p , H , or H with a positive electric charge of +1 e (elementary charge). Its mass is slightly less than the mass of a neutron and approximately 1836 times the mass of an electron (the proton-to-electron mass ratio). Protons and neutrons, each with a mass of approximately one atomic mass unit, are jointly r… See more

    Description

    Protons are spin-⁠1/2⁠ fermions and are composed of three valence quarks, making them baryons (a sub-type of hadrons). The two up quarks and one down quark of a proton are held together by the strong force, mediated by … See more

    History

    The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815, William Prout proposed that all atoms are composed of hydrogen atoms (which he called "prot… See more

    The secrets of protons revealed!
    Protons are one of the three main subatomic particles that make up all the matter we see around us. They are positively charged and form the nuclei of atoms along with neutrons.
    Occurrence

    One or more bound protons are present in the nucleus of every atom. Free protons are found naturally in a number of situations in which energies or temperatures are high enough to separate them from electrons, for which they … See more
