3. Ionic Compounds and Their Properties
An ionic bond is an attraction between oppositely charged ions.
Ionic compounds tend to :
Be brittle solids at room temperature
Have high melting points
Be highly soluble in water
Conduct electricity in solution

4. Covalent Compounds and Their Properties
Covalent compounds are compounds that form when atoms share electrons.
A molecule is the smallest particle into which a covalent compound can be divided and still be the same compound.
Properties of covalent compounds:
Some are not soluble in water
Low melting points
Some do not form ions in water and do not conduct electricity
