What are three physical properties of ionic compounds?

Answer 1

Ionic compounds have six properties. They are hard and brittle, have high melting and boiling points, they are solid at room temperature, they conduct electricity when melted and dissolved in water, are soluble, and form crystals when combined.

Answer 2

Physical Properties of Ionic Compounds:

• Solids at room temperature.
• High melting and boiling points, due to strength of electrostatic bonds.
• Often very soluble in water.
• Low thermal conductivity.
• Only conduct electricity if in liquid and aqueous (if soluble) states, as there are no mobile ions/electrons in lattice in their solid states.

Answer 3

• brittleness
• melting
• high solubility in water
• very high boiling points

Answer 4

They are brittle, theydissolve in water, they have a high melting point, and they share valence electrons.

Answer 5

high melting point, dissolve in water, fourm crystals when solid

Answer 6

Typical ionic compounds have high melting and boiling points, good solubility in polar solvents (water, for example) and low to no conductivity when solid.
high melting point

Answer 7

Five physical properties of ionic substances: density, hardness, melting point, boiling point, thermal conductivity.
