Ionic Crystals (Ionic Solids) Examples: NaCl, MgCl2, MgO, etc Ionic Bonding : Attraction of charged ions for one another. Metallic solids (Metals) Examples: Na, Cu, Fe, Mn , etc Metallic bonding : Valence electrons form mobile sea of electrons which comprise the metallic bond. Substances with high surface tension such as water have very strong intermolecular forces due to hydrogen bonding. The strength of these attractions also determines what changes in temperature and pressure are needed to effect a phase transition. [Show more] Preview 2 out of 10 pages Combine various metal and nonmetal atoms to observe how the electronegativity difference determines the polarity of chemical bonds. Most substances can exist in either gas, liquid, or solid phase under appropriate conditions of temperature and pressure. Intra molecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Ch 3 f dipole ch 3 oh. The instantaneous unequal sharing of electrons causes rapid polarization and counter-polarization of the electron cloud in atoms and molecules which generate (very) short lived dipole moments. This is the average distance that will be maintained by the two particles if there are no other forces acting on them, such as might arise from the presence of other particles nearby. Z.

decreases with increased intermolecular forces, normal boiling point (boiling point at 1 atmosphere pressure) increases with increased intermolecular forces, heat of vaporization (heat requires to take a liquid sample to the gaseous phase) increases with increased intermolecular forces, surface tension (adhesion of molecules) increases with increased intermolecular forces.
