Document Summary

Large atoms with many electrons exhibit a higher polarizability than small atoms: this means that the importance of london dispersion forces increases greatly as the size of the atom increases. Since none of these molecules has a permanent dipole moment, their principal means of attracting each other is through london dispersion forces: 9. 2: the liquid state, liquid characteristics: In the gaseous state the particles are so far apart and are moving so rapidly that intermolecular forces are negligible under most circumstances: this means that we can use a relatively simple model for gases. In metallic solids, a special type of delocalized nondirectional covalent bonding occurs. In network solids, the atoms bond to each other with strong directional covalent bonds that lead to giant molecules, or networks, of atoms. In the second layer the spheres do not lie directly over those in the first layer. Instead, each one occupies an indentation formed by three spheres in the first layer.
