Crystalline solids fall into one of four categories. c. iron(II) nitrite The ease with which metals can be deformed under pressure is attributed to the ability of the metal ions to change positions within the electron sea without breaking any specific bonds. dispersion forces are intermolecular bonds formed in non polar compounds. The strength of metallic bonds varies dramatically. Due to strong covalent bonding within the layers, graphite has a very high melting point, as expected for a covalent solid (it actually sublimes at about 3915C). they allow non polar molecules to form solids, liquids, although the attraction is weak so not much energy is needed to break it. a.

Based on the nature of the forces that hold the component atoms, molecules, or ions together, solids may be formally classified as ionic, molecular, covalent (network), or metallic. It is also very soft; the layers can easily slide past one another because of the weak interlayer interactions. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties. As a result, they tend to be rather soft and have low melting points, which depend on their molecular structure. In metallic solids, the valence electrons are no longer exclusively associated with a single atom.
