Answer 3

Making bonds involve atoms giving away, taking or sharing electrons

(Only the electrons are involved)

Question 4

What do you need a chemical reaction to do ?

Answer 4

You would need a chemical reaction to separate the original elements from the compounds

Question 5

What does a compound that is formed from a metal and a non metal consist of ?

Answer 5

A compound that is formed from a metal and a non metal consists of ions

The metal atoms lose electrons to form positive ions

The non metals gain electrons to form negative ions

Question 6
