recall the simple properties of Groups 1, 7 and 0
physical and chemical properties
explain how observed simple properties of Groups 1, 7 and 0 depend on the outer shell of electrons of the atoms and predict properties from given trends down the groups
ease of electron gain or loss;physical and chemical properties
recall the general properties of transition metals and their compounds and exemplify these by reference to a small number of transition metals
*melting point, density, reactivity, formation of coloured ions with different charges and uses as catalysts *
predict possible reactions and probable reactivity of elements from their positions in the Periodic Table
explain how the reactivity of metals with water or dilute acids is related to the tendency of the metal to form its positive ion
deduce an order of reactivity of metals based on experimental results
