Question 14 • Chemistry

Which statement is true about crystal lattice energy?

Answer
A
It increases as the size of the ions increases.
B
It is a measure of the strength of the bonds between ions.
C
It increases as the charge on the ions decreases.
D
It is the energy that ions absorb when they form a crystal.

Explanation

Crystal lattice energy indicates how strongly oppositely charged ions attract each other in a crystal, so it measures the strength of the bonds between ions. It generally becomes greater when the ions have larger charges or are closer together. Larger ions are farther apart, and lower charges weaken the attraction, so A and D describe the trends incorrectly.
