Outlining the properties and reactions of group 2 metals as needed for Edexcel A-level chemistry, including:

Trend in first ionisation energy and reactivity down the group.
Reactions of the group 2 metals (Mg to Ba) with water
Reactions of the group 2 metals (Mg to Ba) with oxygen
Reactions of the group 2 metals (Mg to Ba) with chlorine
Reactions of the group 2 metal oxides with water and dilute acid
Reactions of the group 2 metals hydroxides with dilute acid
Solubilities of the group 2 metal hydroxides and group 2 metal sulfates
Trend in thermal stability of the nitrates and carbonates for the group 2 elements, based on size and charge of cations involved. Can be observed experimentally as the greater the thermal stability of the substance, the more heat that’s required for thermal decomposition.
