Question 13

bonds - ionic bonding?

Answer 13

The positive and negative charges are held together by the strong electrostatic forces of attraction between oppositely charged ions

Question 14

giant ionic lattice?

Answer 14

Ionic compounds are made of charged particles called ions which form a giant lattice structure

Question 15

melting point of ionic substances?

Answer 15

high melting and boiling points due to the presence of strong electrostatic forces acting between oppositely charged ions

Question 16

are ionic compounds conductive?

Answer 16

• only when in molten state or in solution as they have ions that can move and carry charge

Question 17

Why can ionic compounds conduct electricity in the solid state?

Answer 17

the ions are in fixed positions within the lattice and are unable to move
