#C4.1a
recall the simple properties of Groups 1, 7 and 0
physical and chemical properties
#C4.1b
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
#C4.1c
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
#C4.1d
predict possible reactions and probable reactivity of elements from their positions in the Periodic Table
#C4.1e
explain how the reactivity of metals with water or dilute acids is related to the tendency of the metal to form its positive ion
#C4.1f
deduce an order of reactivity of metals based on experimental results
