Question 14

True or false: Ionic solids are malleable (can bend + shape)

Answer 14

False

Question 15

Can ionic solids conduct electricity?

Answer 15

They cannot when they are a solid crystal due to its ions not being able to move freely to carry an electric charge.

Question 16

What happens when ionic solids/compounds are melted or dissolved in water?

Answer 16

The liquid of the ionic compound conducts electricity due to the ions being able to move freely.

Question 17

Melting point

Answer 17

Temperature at which a solid substance turns into a liquid.

Question 18

Boiling point

Answer 18

Temperature at which a liquid substance turns into a gas

Question 19

Answer 19

Hold the substance’s particles together.

Question 20

Lots of heat/not a lot of heat are required…

Answer 20

To overcome the attractive forces within the substance

Question 21

Lewis Diagrams

Answer 21

Shows how the atoms in a molecule bond to each other with non-bonding & bonding electrons
