1 PERIODICITY Elements are classified into metals, nonmetals and metalloids. Metals are on the left side while the nonmetals are toward the upper right of the table. Metalloids have properties of metals and nonmetals and are found bordering the diagonal line. Periodic trends in atomic properties ± Effective nuclear charge ± Atomic and ionic radii ± Ionization energy ± Electron affinity ± Electronegativity ± Oxidation states

2 STATES OF MATTER LIQUIDS AND SOLIDS Kinetic molecular theory ± Physical properties of liquids or solids are due to intermolecular forces. ± Intermolecular forces are forces between molecules and are weaker than ionic and covalent bonds. ± The kinetic energy of a particle is inversely related to the interparticle force of attraction. ± KE depends on temperature and tends to keep the particles apart and moving.

Unformatted text preview: ± Interparticle attractions tend to draw the particles together. ± Physical properties of liquids or solids are due to intermolecular forces. Intermolecular forces Van der Waals forces are the intermolecular forces that exist between neutral molecules. ± Ion-dipole forces ± Dipole-dipole forces ± London dispersion forces ± Hydrogen bonding 3 Heating and cooling curves This is a graph of the temperature of a system versus the amount of heat added or lost. Phase diagram This is a graphical way to summarize the conditions under which equilibria exist between the different states of matter. Phase changes ± Vaporization ± Boiling point ± Melting point/freezing point ± sublimation...
