  • Ionic Compound
    A substance composed of a large network of positive and negative ions held together by electrostatic attraction in a crystal lattice.
  • Formula Unit
    The simplest ratio of ions that results in electrical neutrality within an ionic solid.
  • Crystal Lattice
    A three-dimensional, repeating arrangement of cations and anions forming a stable structure in ionic solids.
  • Cation
    A positively charged ion, typically formed by metals, that participates in forming ionic compounds.
  • Anion
    A negatively charged ion, usually derived from nonmetals, that pairs with cations in ionic compounds.
  • Polyatomic Ion
    A charged group of covalently bonded atoms acting as a single ion in ionic compounds, such as PO4^3−.
  • Empirical Ratio
    The lowest whole-number proportion of ions present in an ionic compound's formula unit.
  • Parenthesis
    A notation used in chemical formulas to indicate that a subscript applies to an entire polyatomic ion.
  • Charge
    An electrical property of ions, indicated by a superscript, that determines how ions combine to form neutral compounds.
  • Periodic Table
    A chart organizing elements by atomic number and properties, used to predict common ionic charges.
  • Group
    A vertical column in the periodic table indicating panatomic trends, such as typical ionic charges for elements.
  • Subscript
    A small number written below and to the right of a chemical symbol, showing the quantity of atoms or ions in a formula.
  • Neutrality
    The state achieved when the total positive and negative charges in a compound balance to zero.
  • Ionic Solid
    A rigid structure formed by a vast network of alternating cations and anions in a crystal lattice.
  • Tetraoxide
    A polyatomic ion containing four oxygen atoms, as seen in phosphate (PO4^3−).
