What are 4 characteristics of ionic solids?
- They form crystals.
- They have high melting and high boiling points.
- They are hard and brittle.
- They have higher enthalpies of fusion and vapourisation than molecular compounds.
- They conduct electricity when dissolved in water.
- Ionic solids do not conduct electricity so they are good insulators also.
What are 3 basic characteristics of ionic compounds?
What characteristics do ionic compounds have?
They are usually crystalline solids. They have high melting points and high boiling points. They are usually soluble in water but insoluble in organic solvents. They conduct electricity when dissolved in water or when melted.

Which of the following are physical properties of ionic solids?
Are ionic solids soluble?
If the solution forms with a drop in total energy change of dissolving, DEtotal < 0, the ionic solid is soluble. If the solution forms with an increase in total energy change of dissolving, DEtotal > 0, the ionic solid is insoluble.
Are ionic solids soft?
Why ionic solids are hard and brittle?

What are three properties of covalent compounds?
- Have low boiling points and melting points.
- Generally are poor conductors of heat and electricity.
- Exist as brittle solids.
What are characteristics of covalent compounds?
- The covalent compounds exist as gases or liquids or soft solids.
- The melting and boiling points of covalent compounds are generally low.
- Covalent compound are insoluble in water but dissolve in organic solvents.
- They are non-conductors of electricity in solid, molten or aqueous state.
