  • Subatomic Particles
    Fundamental components of an atom, including neutrons, protons, and electrons.
  • Neutrons
    Neutral particles in an atom's nucleus, slightly heavier than protons.
  • Protons
    Positively charged particles in an atom's nucleus, similar in mass to neutrons.
  • Electrons
    Negatively charged particles with much less mass than protons or neutrons.
  • Nucleus
    Central part of an atom containing protons and neutrons, accounting for most of its mass.
  • Atomic Mass Unit
    Unit of mass equal to 1/12 the mass of a carbon-12 atom, also known as Dalton.
  • Dalton
    Alternative name for atomic mass unit, named after John Dalton.
  • Coulombs
    Unit of electric charge, used to express the actual charge of protons and electrons.
  • Relative Mass
    Mass of subatomic particles expressed in atomic mass units for comparison.
  • Relative Charge
    Charge of subatomic particles expressed as +1, 0, or -1 for protons, neutrons, and electrons.
  • Actual Mass
    Mass of subatomic particles measured in kilograms.
  • Actual Charge
    Charge of subatomic particles measured in coulombs.
  • Carbon-12
    Isotope of carbon used as a reference for defining atomic mass units.
  • John Dalton
    Chemist known for his work on atomic theory, after whom the Dalton unit is named.
