Bonding
In the everyday world around us, we observe three very different types of materials: gases, liquids, and solids. Closer examination of the physical properties of
homogeneous
crystalline solids shows that they can be subdivided into four distinct categories according to their physical properties and the different forces holding them together. For each category, we must develop a bonding picture, based on electrons, that will lead to an understanding of the physical properties exhibited. We can classify the solids according to the distribution of the
valence
electrons of the atoms (as shown in Figure 1), which explains their physical properties.
Types of Solids
