3.3.4 - Ionic Properties

Question 1

Do ionic compounds have a low melting point !?

Answer 1

. No, ionic compounds have high melting points

Question 2

Are ionic bonds weak or strong !?

Answer 2

. Ionic bonds are VERY STRONG

Question 3

Does breaking ionic bonds require a large amount of energy !?

Answer 3

. Yes, breaking all the ionic bonds requires a LARGE AMOUNT OF ENERGY

Question 4

Why might some ionic compounds have a HIGHER melting point then others !?

Answer 4

. Because their ions have HIGHER CHARGES. This makes the attraction between the ions EVEN STRONGER and harder to break

Question 5

Do ionic compounds conduct electricity !?

Answer 5

. Ionic compounds only conduct electricity under certain circumstances :
- when liquid (l) or dissolved (aq)

Question 6

When do ionic compounds not conduct electricity !?

Answer 6

. When in SOLID (s) form
