Group II reactions cover the behaviour of beryllium, magnesium, calcium, strontium and barium with water, oxygen, halogens, acids and nitrogen. The trends in reactivity, hydroxide solubility and basicity, along with the thermal decomposition of carbonates and nitrates, depend on increasing atomic size down the group.
