📖 Key Definitions
Ionic bond: The electrostatic force of attraction between oppositely charged ions, formed when electrons are transferred from a metal to a non-metal.
Ion: A charged particle formed when an atom loses or gains one or more electrons.
Cation: A positively charged ion, formed when a metal atom loses electrons (e.g., Na⁺, Mg²⁺).
Anion: A negatively charged ion, formed when a non-metal atom gains electrons (e.g., Cl⁻, O²⁻).
Electrostatic attraction: The force of attraction between oppositely charged particles — the fundamental force that holds ionic bonds together.
Electron transfer: The movement of electrons from one atom to another, converting neutral atoms into ions.
