Answer

A material in which atomic bonding is predominantly ionic in nature is less likely to form a noncrystalline solid upon solidification than a covalent material. This is because covalent bonds are directional whereas ionic bonds are non directional. It is more difficult for the atoms in a covalent material to assume positions, giving rise to an ordered structure.
