1

## How do ions in ionic compounds achieve stability?

### Their electron configuration is the same as a noble gas after they have gained/lost an electron

2

## What is an ionic bond?

### The electrostatic force of attraction between the two oppositely charged ions

3

## Will ionic bonds exist in isolation?

### No, they will always form part of a giant ionic lattice

## When two ions are more charged, what will this mean for the forces of attraction between them?

### The more charged the ions are, the greater force of attraction between them
