WebWhereas the characteristic melting point of metals and ionic solids is ~1000 °C, most molecular solids melt well below ~300 °C. Thus, many corresponding substances are either liquid (water) or gaseous (oxygen) at room temperature. Molecular solids also have relatively low density and hardness. WebProperties and several examples of each type are listed in the following table and are described in the Table below. 1. Ionic crystals -- The ionic crystal structure consists of alternating positively-charged cations and negatively-charged anions (see Figure below ). The ions may either be monatomic or polyatomic.
