3.3+Chemical+properties

Learning Goals: (3 hours)
 * Discuss the similarities and differences in the chemical properties of elements in the same group. (Alkali metals (Li, Na and K) with water. Alkali metals (Li, Na and K) with halogens (Cl2, Br2 and I2) Halogens (Cl2, Br2 and I2) with halide ions (Cl–, Br– and I–))
 * Discuss the changes in nature, from ionic to covalent and from basic to acidic, of the oxides across period 3. (Equations are required for the reactions of Na2O, MgO, P4O10 and SO3 with water.)
