Ionic solids are a type of solid structure where the constituent particles are ions held together by ionic bonds. These solids often exhibit high melting and boiling points, are good conductors of electricity in molten or aqueous states, and have a crystalline structure. Examples include common table salt (NaCl) and magnesium oxide (MgO).
Ionic solids are typically harder than molecular solids because ionic bonds are stronger than intermolecular forces found in molecular solids. The ionic bonds in ionic solids result from the attraction between positively and negatively charged ions, contributing to their higher hardness compared to molecular solids, which are held together by weaker intermolecular forces.
Molecular solids
Covalent solids typically have lower melting points than ionic solids because the intermolecular forces holding covalent compounds together are weaker than the ionic bonds in ionic solids. Molecular substances, like water and carbon dioxide, also have lower melting points than ionic solids due to the weaker forces between individual molecules.
No, gold and platinum are not ionic solids. They are metallic elements that form metallic bonds with delocalized electrons. Ionic solids are formed by the electrostatic attraction between positively and negatively charged ions.
Ionic solids tend to be the strongest because they have strong electrostatic forces between positively and negatively charged ions. Metallic solids have a delocalized electron sea that allows for high conductivity but not necessarily the same level of strength as ionic solids. Covalent solids have strong covalent bonds but may not be as strong as ionic solids due to the lack of strong electrostatic interactions.

Molecular solids
Ionic solids are not dissociated in ions.

it melts
Ionic solids most likely dissolve in water because water is a polar solvent.
Covalent solids and molecular solids typically have lower melting points than ionic solids. This is because the intermolecular forces holding covalent and molecular solids together are generally weaker than the electrostatic forces binding ionic solids, resulting in lower energy requirements for melting.
Molecular solids have lower boiling points than ionic solids because the intermolecular forces between molecules in a molecular solid are weaker than the electrostatic forces between ions in an ionic solid. As a result, less energy is required to break apart the molecular interactions and transition to the gaseous phase in molecular solids compared to ionic solids with stronger ionic bonds.
