#6.1
Explain why some elements can be classified as alkali metals (group 1), halogens (group 7) or noble gases (group 0), based on their position in the periodic table
#6.2
Recall that alkali metals:
a) are soft
b) have relatively low melting points
#6.3
Describe the reactions of lithium, sodium and potassium with water
#6.4
Describe the pattern in reactivity of the alkali metals, lithium, sodium and potassium, with water; and use this pattern to predict the reactivity of other alkali metals
#6.5
Explain this pattern in reactivity in terms of electronic configurations
