Lab 3.1 Modeling Of Molecules.

1. The attraction between ions is stronger Al₂O_{3 which is an ion melt  at} 2072^oC  _{Which is a higher melting point and they tend to be hard. Also Ions are electrically conductive and very aqueous ( conduct in liquid). Covalent bond are typically soft, have low melting point and aren't electrically conductive.}
2. _{The process of melting is a physical change so when HCL molecules are melted we will still have HCL because nothing new was formed and when physical change occur the original material can generally be recovered.}
3. _{Ionic compounds can conduct electricity because they transfer electrons , and this cause them to have positive charges. However when Ionic compounds are solid they cannot conduct electricity because they're not moving, so no electricity is being conducted.}
4. _{Molecular substances lack the ability to conduct electricity in either solid or liquid form because molecular substances share electrons, therefore there's no positive charges, so no electricity can be conducted.}
