Which of the following are characteristics of ionic
Margarita [4]

Answer:

  • have high melting and boiling points
  • are hard
  • are good conductors of electricity when  dissolved in water

Explanation:

Ionic compounds are compounds that are formed between a metal and non-metal with a significant electronegativity difference. The metals transfers their electrons to the non-metals and the electrostatic attraction of the ions brings about the bonding that forms the compound.

Ionic compounds are diverse in nature and form.

Here are some of their properties:

  • They are usually hard solids with a high melting point or liquids with high boiling points
  • They are soluble in water and non-soluble in non-polar solvents
  • They are able to conduct electricity in molten form.
  • They undergo very fast reaction in aqueous solutions.
