Magnesium is a metal.

1. (a)State two properties which are characteristic of most metals. 1 2[2]
2. (b)Complete the electronic configuration of a magnesium atom. Show all electrons. [Diagram showing a central 'Mg' label with three concentric empty circles for electron shells][1]
3. (c)(i)Magnesium reacts with bromine to form magnesium bromide, MgBr₂. Magnesium bromide is an ionic solid at room temperature. Explain, in terms of movement of electrons, how magnesium bromide is formed by the reaction of magnesium with bromine.[3]
4. (c)(ii)Magnesium bromide is soluble in water. Suggest one other physical property of magnesium bromide.[1]
5. (d)Deduce the products formed at the anode and cathode when concentrated aqueous magnesium bromide is electrolysed. product at anode product at cathode[1]
6. (e)(i)Chlorine reacts with aqueous magnesium bromide. The products are aqueous magnesium chloride and aqueous bromine. Construct the ionic equation for this reaction.[1]
7. (e)(ii)Explain why aqueous magnesium chloride does not react with aqueous bromine.[1]
