* Orderly Crystal Shapes: Ionic compounds form crystal lattices, which are highly ordered and repeating three-dimensional structures. This is why they often exhibit well-defined, geometric shapes.
* High Melting Points: Ionic compounds have strong electrostatic attractions between their oppositely charged ions. These attractions require a lot of energy to overcome, leading to high melting points.
* Electrical Conductivity when Dissolved in Water: When ionic compounds dissolve in water, their ions become free to move about. This allows the solution to conduct electricity.
In summary: Yes, orderly crystal shapes, high melting points, and electrical conductivity when dissolved in water are all properties characteristic of ionic compounds.
Key takeaway: These properties are a result of the strong electrostatic forces holding the ions together in the solid state and their ability to dissociate and move freely in solution.
