As single ions of a metal are not associated in the solid with single ions of a non metal, separate units of ionic compounds do not exist. It is, therefore, wrong to talk of a molecule of an ionic compound. I know ionic solids exist in form of crystal lattice but why can't we isolate a single molecule of ionic compound?
I assume it just means that it is difficult to separate elements in compounds because there is strong electrostatic force between either the nuclei and the other ions' electrons (ionic) or in sharing electrons (covalent).
Because ionic compounds are formed by alternating positive and negative ions, and because they are all held together with these strong electrostatic forces, the oppositely charged ions pack tightly with each other and form a crystal lattice structure that is extremely hard to break.

would have to be overcome by adding energy to the ionic compound in the form of heat. This takes a lot of heat, so ionic compounds have melting and boiling points in the hundreds or thousands of degrees Celsius.
Ionic compounds are very hard and very fragile. Again, it is because of how they stick together. Above we said that it takes a lot of energy to break the positive and negative charges apart. This is why ionic compounds are so difficult - it simply does not move much, so it does not bend at all. This also explains the fragility of the ionic compounds.
Why are ionic compounds hard? The great resistance to movement that comes are a result of the attraction between their positive and negative Moving ions are one way in which electricity can be conducted, and when ionic compounds are either melted or dissolved, they are free to move around.
3. Molten ionic compounds can conduct electricity because the ions are free to move around within the molten compounds. Ionic compounds in solution can conduct electricity because the water molecules separate ions from the lattice meaning ions are free to move around within the solution. 4. The ions are fixed in the lattice.
ionic compound are hard solid bcz it is held togather by strong electrostatic force of attracton beetween positve and negative ions so it is hard crystaline solid

Ionic compound are made up of ions rather than molecules. Ionic compounds are materials whose atoms have formed ionic bonds rather than molecules with covalent bonds. Ionic compounds have high melting and boiling points, may form crystals and are generally hard and brittle.
Ionic compounds are usually hard because they r held together by strong electrostatic forces of attraction. Therefore the oppositely charged ions pack tightly with each other and form a crystalline structure which is very hard to break down.
Ionic compounds are solids and hard due to the strong attracting force between the positive and negative ions. These compounds are generally brittle and break into pieces on application of pressure. Ionic compounds have high melting and boiling points because a application of significant amount of energy can break the strong inter-ionic attraction.
Table salt is an ionic compound and is brittle. But diamond is also brittle despite being a molecular solid where all the carbon-carbon bonds are covalent. Glass is very strong but, like salt, very brittle which is why dropping your phone on hard surfaces is a bad idea. Toughness is a better term for the...
Dec 06, 1999 · Ionic Compounds Ionic compounds are characteristically hard , usually with high melting points, and very brittle . The hardness and high melting points are down to their crystal structure; as long as the lattice holds, they are solid and quite strongly bonded.
