Chapter 4 - Reactions of ionic compounds Flashcards
Anion
negative ion formed when an atom gains one or more valence electrons
Brittle
tendency of a material to fracture (break) when subjected to pressure
Coordination number
the number of atoms, molecules or ions bonded to a chemical species
Crystal lattice (ionic)
symmetrical, three-dimensional arrangement of ions
Hardness
resistance to deformation when subjected to pressure
Ion
atom that has lost or gained electrons to become a charged particle
Melting point
temperature at which a substance changes its state from solid to liquid
Molten
a pure substance that has been liquefied by heat
Ionic bond
electrostatic force of attraction between cations and anions
Ionic compound
compound made up of cations and anions held together by electrostatic forces of attraction
Monatomic ion
ion made up of only one atom
Polyatomic ion
ion made up of a group of atoms covalently bonded together
Aqueous
dissolved in water
Dissolved
incorporated into a liquid to form a solution
Full equation
chemical equation with all chemical species present
