Web7 jan. 2015 · In covalent molecules, there’s a theory that the bigger the molecule, the higher the melting point and boiling point. However, the main reason why giant covalent structures have high melting and boiling point is that it is the strong covalent bond that must be overcome in order to melt or boil the giant covalent structure. WebWhat does ionic, covalent, and Metallic Bonding all have in common? The fact that they can all form lattice structures. Because each lattice has a structure and bonding of different types, this causes them to have different physical properties, such as differences in solubility, melting point, and conductivity, which can all be explained by their varying … ghana lowest point
