All 50 states have a 21 year old minimum drinking age according to the national drinking age act of 1984.
Answer:MgO>CaO>NaF>KCl
Explanation:
The lattice energy is one that depend on the attraction between oppositely charged ions in a compound/substance.
Following up with this the greatest forces of attraction will exist between ions that have the smallest radii.
And, because the attraction depends on the product of the charges, we prioritize ions with the greatest charge.
The smallest pair of ions will be able to get closest to each other relative to others. This implied that the smallest distance between centres will have the largest lattice energies relative to others.
I believe it is A. Just don't hold me down on that. :D
