Draw a labelled diagram to illustrate the bonding and structure of the Group 2 metals at room temperature.
Explain why Mg has a higher electrical conductivity than Na.
Write an equation for how magnesium reacts with cold water.
Identify one reagent that could distinguish between separate samples of dilute $\text{Mg(NO}_3)_2\text{(aq)}$ and dilute $\text{Ba(NO}_3)_2\text{(aq)}$. Explain your answer.
Describe the observations when $\text{SrI}_2\text{(aq)}$ reacts with concentrated sulfuric acid.
Compound $X$, an anhydrous Group 2 bromide, is dissolved in water and titrated with aqueous silver nitrate. A solution containing $0.250\,\text{g}$ of $X$ needs $33.65\,\text{cm}^3$ of $0.0500\,\text{mol dm}^{-3}$ $\text{AgNO}_3\text{(aq)}$ for complete reaction. Identify $X$. Show your working.
