what are the characteristics of ionic solids?
444981
Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl.

Network solids have similar properties to ionic solids. They are very hard, somewhat brittle solids with extremely high melting points (higher than 1,000 C or 1,800 F). Unlike ionic compounds, they do not dissolve in water, nor do they conduct electricity.
624226
Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move. Ionic compounds are conductors of electricity when molten or in solution, and insulators when solid.

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.

The key difference between ionic and metallic solids is that ionic solids essentially contain cations and anions, whereas metallic solids contain metal atoms and free electrons. Moreover, the ionic solids have electrostatic attraction forces between cations and anions, while the metallic solids have metallic bonds.

Ionic Solids are solids composed of oppositely charged ions. They consist of positively charged cations and negatively charged anions . When Ionic Solids are dissolved in water the cations and the anions separate, they become free to move about in the water allowing the solution to conduct electrical current.

The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points. ... The strong bonds between their oppositely charged ions lock them into place in the crystal.

In ionic compounds, electrons are tightly held by the ions, and the ions cannot move translationally relative to each other. This explains many properties of ionic solids. They are hard and brittle, they are not malleable or ductile (i.e. cannot be shaped without cracking/breaking), and they do not conduct electricity.

Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.

Ionic solids are very hard and brittle. Hard due to the strong bonds. Brittle since when distorted like charged ions move closer to each other and the strong electrostatic repulsions shatter the crystal. Ionic solids cannot conduct electricity.
