Study Notes

Ionic Compounds

An ionic compound is formed when a metal reacts with a nonmetal or a polyatomic ion.
An ion is formed when an atom gains or loses electrons.
Cations are positively charged ions (formed by losing electrons).
Anions are negatively charged ions (formed by gaining electrons).
An ionic compound is formed by the electrostatic attraction between cations and anions.
Ionic compounds have a crystal lattice structure.
Lattice energy is the energy required to separate one mole of a solid ionic compound into its gaseous ions. A higher lattice energy indicates a stronger bond.
Ionic compounds generally have high boiling points and melting points. They are typically solids at room temperature.
Ionic compounds are brittle.
They conduct electricity only when molten or dissolved in solution, not as solids.
