Question

Would MgO or NaF have the larger lattice energy? justify your answer

Answer 1

Would not magnesium oxide exhibit the greater lattice energy....?

Explanation:

We are asked to assess lattice energy with no other data but the formula of each salt. We would anticipate that the lattice energy of `MgO` formed from `Mg^(2+)` and `O^(2-)` ions SHOULD be greater than that of `Na^(+)F^(-)` formed from ions of a single charge.... This should also be reflected in the physical properties of each salt (and these are unstated....look them up, melting point, solubility, etc.).
