Ionic Bond: A type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically resulting from electron transfer between metals and nonmetals.
Cation: A positively charged ion formed when an atom loses one or more electrons (e.g., Na⁺).
Anion: A negatively charged ion formed when an atom gains one or more electrons (e.g., Cl⁻).
Electronegativity Difference: The difference in electronegativity values between two atoms; a difference greater than 1.7 generally indicates ionic bonding.
Lattice Structure: The regular, repeating three-dimensional arrangement of ions in an ionic compound, maximizing electrostatic attraction.
Ionic Compound: A compound composed of ions held together by ionic bonds, exhibiting high melting points, solubility in water, and electrical conductivity in molten or aqueous states.
