Chemical Structures.Ionic Structures - The electrostatic force of attraction between positively and negatively charged atoms. - Very Strong Bonds - High melting and boiling points - Conductive in a solutionCovalent Structures - Two oppositely charged ions are recharged in a regular way - They form giant lattices - Low melting and points - Non-metal to non-metal - Examples include; water and chlorine gasMetallic Structures - Metal to metal - Solids - Free electrons - High melting and boiling points
