Im pretty sure the answer is D, I may be wrong tho
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.
They move faster and move farther apart

First you find the frequency which is. 1/T(period) so u get 1*10^10
Now that you know frequency u can solve for speed: s= wavelength* frequency, but don't forget to convert 3cm into meters: 3/100= .03m so now you do (1*10^10)(.3)= 300,000,000 m/s or 3*10^8 m/s
Hope this helped :))
