  • Atom
    Smallest unit of an element, serving as the basic building block in chemistry, composed of a nucleus and surrounding electrons.
  • Nucleus
    Central region of an atom, extremely small compared to the atom's total volume, containing protons and neutrons.
  • Proton
    Positively charged subatomic particle found within the nucleus, contributing to the atom's identity and charge.
  • Neutron
    Neutral subatomic particle located in the nucleus, acting as a stabilizing 'glue' between protons.
  • Electron
    Negatively charged subatomic particle orbiting the nucleus, occupying a region vastly larger than the nucleus itself.
  • Electron Cloud
    Region surrounding the nucleus where electrons are likely to be found, much larger in volume than the nucleus.
  • Subatomic Particle
    Constituent of atoms, including protons, neutrons, and electrons, each with distinct charge and location.
  • Nuclear Force
    Attractive interaction within the nucleus that binds protons and neutrons together, overcoming repulsive forces.
  • Electrostatic Force
    Repulsive interaction between like-charged protons in the nucleus, tending to push them apart.
  • Stability
    Condition where the nucleus remains intact, achieved when attractive forces exceed repulsive ones.
  • Positive Charge
    Electrical property associated with protons, leading to repulsion between similar particles in close proximity.
  • Negative Charge
    Electrical property associated with electrons, resulting in attraction to positively charged particles.
  • Neutral Charge
    Absence of electrical charge, characteristic of neutrons, preventing repulsion or attraction within the nucleus.
  • Volume
    Space occupied by the atom, with the electron cloud accounting for nearly all of it compared to the nucleus.
  • Element
    Substance consisting of atoms with the same number of protons, defining its chemical identity.
