    Study Notes

    Properties of Subatomic Particles

    • Subatomic particles include protons, neutrons, and electrons, each with distinct properties.
    • Proton symbol: p+, with a relative charge of +1, found in the nucleus with a mass of 1 amu.
    • Neutron symbol: n0, has no charge (0), located in the nucleus, also with a mass of 1 amu.
    • Electron symbol: e-, carries a relative charge of -1, exists outside the nucleus with a much smaller mass of 1/1840 amu.
    • Protons were pioneered by Eugen Goldstein and named by Ernest Rutherford.
    • James Chadwick discovered neutrons, while Joseph John Thomson is credited with the discovery of electrons.

    Atomic Number (Z)

    • The atomic number (Z) represents the count of protons in an atom.
    • Formula: Z = number of protons (p+).
    • In a neutral atom, the number of protons equals the number of electrons, balancing the overall charge.
