C4.1: Predicting chemical reactions

#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

C3.4
Electrolysis
C4.2
