To make life a bit easier remember these questions 1. Is it a metal or a non metal? 2. Is it a plus or a minus? 3. Valance Number ? You DO remember valance numbers??

The ION Let’s try Aluminium 1. Is it a metal or a non metal? 2. Is it a plus or a minus? 3. Valance Number ? METAL Al PLUS + 3 3

The ION Let’s try Sulphur 1. Is it a metal or a non metal? 2. Is it a plus or a minus? 3. Valance Number ? NON-METAL S MINUS - 2 2

Lots of Happy Ions
