Why ionic crystals are hard and brittle? - Sarthaks eConnect Large…
WebSep 20, 2024 · Ionic compounds are generally hard, but brittle. Why? It takes a large amount of mechanical force, such as striking a crystal with a hammer, to force one layer of ions to shift relative to its neighbor. However, when that happens, it brings ions of the same charge next to one another (see below). WebIonic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to see how bonding and … hora new brunswick
