Ionic compounds

Question 1

Ionic compound

Answer 1

Metal reacts with a non metal

Question 2

Ionic bonding

Answer 2

Electrostatic force of attraction between oppositely charged ions

Question 3

Ionic compound properties

Answer 3

High melting temperature
Hard and brittle
When molten or dissolved in water, conduct electricity

Question 4

High melting temperature

Answer 4

Electrostatic attraction is very strong and a high temperature is required to disrupt the crystal lattice

Question 5

Hard and brittle

Answer 5

layers of ions will move relative to each other due to an applied external force
ions of like charge become adjacent
repulsion will cause the crystal to shatter

Question 6

Conduct electricity in liquid or molten form

Answer 6

In solid state ions are held in fixed positions in the ionic lattice and not free to move
when melted or dissolved in water, the ions separate and are free to move

Question 7

Electrovalency

Answer 7

Charge on an ion
