Group 2 And Group 17 Elements

Question 1

Describe the reactivity of group 2 elements down the group, referring to the data booklet

Answer 1

Concept: reactivity of group 2 elements —> look at E value

Down the group, E value becomes increasingly negative, suggesting that the tendency for oxidation of the group 2 metals increases. Reducing power down the group increases, hence reactivity increases
