A student makes three statements about solid magnesium chloride, MgCl2\mathrm{MgCl_{2}}MgCl2.
Statement 1: each Mg2+\mathrm{Mg^{2+}}Mg2+ ion is attracted to all of the Cl−\mathrm{Cl^{-}}Cl− ions around it, not just to two of them
Statement 2: the lattice has no overall charge because it contains equal numbers of positive and negative ions
Statement 3: the ions vibrate about fixed positions and cannot move through the lattice
Which statements are correct?
1 and 3 only
2 and 3 only
1 and 2 only
1, 2 and 3
