Ionic compounds are usually formed between a metal element and a non metal element in most cases. There are some exceptions such as ammonium nitrate though.
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 typically have high melting points due to the strong electrostatic forces binding the positive and negative ions together in a lattice structure. When heated, these bonds must be overcome, requiring a significant amount of energy, resulting in high melting points.
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.

Salts typically form ionic solids, which are made up of positive and negative ions held together by ionic bonds. These solids have a crystal lattice structure and are typically hard and brittle.

Ionic solids are not dissociated in 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.
