Section 3 Ionic Bonding and Ionic Compounds
Chapter 6
Ionic vs. Molecular Compounds
Molecular compounds have relatively weak forces between individual molecules.
They melt at low temperatures.
Ionic compounds contain strong attraction between ions
very high melting points
hard but brittle
not electrical conductors in the solid state, because the ions cannot move

Polyatomic Ions
Polyatomic ion - charged group of covalently bonded atoms with both molecular and ionic properties.
Ex:
One electron is lost during bonding
