Which is the reason that ionic compounds are brittle? The bonds between the anions and cations are weak and therefore easily bro
ken. A strong repulsive force is created when cations suddenly align. They involve positive metal ions in a sea of delocalized electrons. They share electrons, which makes the bond brittle.
Well ionic compounds are brittle because similar charges repel, which causes them to break usually occurring when a force is applied, like a hammer strike.
