Topic 2.6 Properties of Ionic, Covalent, and Metallic Bonds

​Ionic compounds have very strong bonds. This causes ionic compounds to have high melting points and boiling points

​​Strong bonds

​Ionic compounds are made of ions. When you dissolve ionic compounds in water, the ions become mobile and can conduct an electric current

​​Conductive

​Ionic compounds have a crystal lattice structure and are generally solid at room temperature. Think about table salt!

​​Crystalline

IONIC COMPOUNDS

Covalent compounds have weaker bonds ionic compounds. This causes covalent compounds to have low melting points and low boiling points

​​Weak bonds

​Ionic compounds are not made of but are composed of atoms. When you dissolve covalent compounds in water they DO NOT dissociate into ions and therefore, do not conduct a current.

​​Conductive

​Covalent compounds have a Lewis Structures that show their arrangement. They are generally solids, liquids and gases and room temperature. If a solid then dull and brittle

COVALENT COMPOUNDS
