    Are the lattice structures the same size?

    Ok im not 100% sure, but:
    -MgCl2 would dissociate in 3 ions and MgO 2
    - I was trying to link it to the charges (of Cl and O, and repulsion between electrons. But im not too sure

    So basically instead of 1:1 ratio in MgO it will be 1:2 in MgCl2 so there will be double the chloride ions compared to the oxide ions
