Reactivity of group 2 metals increases down the group because...
electrostatic attraction between +ve ions and delocalised electrons decreases
shielding effect decreases down the group
outer electrons are further away from the nucleus so metals easily oxidise
melting point decreases down the group so electrons are easily lost
Group 2 metals are strong reducing agents. Reducing power............. down the group.
increases
decreases
is constant
varies
