Question

Which is the reason that ionic compounds are brittle?

A. The bonds between the anions and cations are weak and therefore easily broken.

B. A strong repulsive force is created when cations suddenly align.

C. They involve positive metal ions in a sea of delocalized electrons.

D. They share electrons, which makes the bond brittle.

Answer 1

Ionic bonds are the weakest bonds. 

Answer 2

The answer is: B. A strong repulsive force is created when the cations suddenly line up.

Step-by-step explanation:

Solid ionic compounds are fragile. This behavior is explained as a result of the repulsions that appear when one layer of ions moves with respect to the other so that ions of the same charge are stopped.

The answer is: B. A strong repulsive force is created when the cations suddenly line up.
