WebMay 21, 2015 · Typically a pure element or an inorganic or organic compound can be made in crystalline form. It might be a fine powder or small granular crystals. If grown under controlled conditions, you could get large crystals. If it is a gas or liquid at room temperature, it could perhaps solidify to a crystalline form at lower temperatures. WebMolecular solids: They are categorised into polar, non-polar, and H-bonded molecular solids. Polar solids constituents have polar bonds and strong dipole-dipole interactions. They are mostly gases or liquids at room temperature. Examples: HCl and ammonia. Non-polar solids are insulators with low melting points in which constituents have non ...
WebA crystalline solid, like those listed in Table 10.4, has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Thus, the attractions between the units that make up the crystal all have the same strength and all require the same amount of energy to be broken.
