CHM110H5 Chapter 4.5: Crystal Properties
Document Summary
However, their a ect is minor and overshadowed by the stronger forces present. Note: the term polar is used interchangeable with polar covalent . Likewise, nonpolar and nonpolar covalent mean the same thing. There are some compounds that do not have molecules, but instead are long chains of covalent bonds (e. g. diamond) This happens in 3 dimensions, creating a crystal. Because there are only covalent bonds, network solids are extraordinarily strong. Metals normally occur as solids (high melting points). bond. Thus, there must be strong bonds between the atoms of metals causing them to nuclei exist in a sea of electrons (this explains why metals conduct electricity) Bonding in metals and alloys is di erent from in other compounds: positive. There are 6 types of intermolecular forces have a common frame of reference. These forces are associated with certain crystal types. Properties of crystals between molecules are overcome and a change of state occurs.
