Answer 2

Why? @akash123

Answer 3

lattice energy follows Coulomb's Law for charged particles, which varies by:\[\frac{Q_1*Q_2}{r^2}\]
where Q are the charges of the ions, and r is the distance between them. When the ions have a large charge (+2)(-2), or (+3)(-3), then the attraction is larger. When the ions have a small radius, the attraction is also stronger, because they are closer together. Large ions have large r-values, so a smaller attraction.
