Properties of ionic compounds

Question 1

describe the structure of a giant ionic lattice

Answer 1

An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice. The lattice is formed due to electrostatic forces

Question 2

list the properties of ionic compounds

Answer 2

• High melting and boiling points

- Don’t conduct electricity in a solid but do in a liquid or a gas.

Question 3

Why do ionic compounds have high melting and boiling points

Answer 3

Because a lot of energy is needed to break through the electrostatic forces and the many strong bonds

Question 4

Why do ionic compounds not conduct electricity in a solid

Answer 4

The ions are in a fixed position and therefore can’t carry the current. However when melted their ions are able to move and are free, therefore able to carry current
