AQA GCSE Chemistry Bonding Revision
Questions with Verified Answers 2026–2027
What elements bond in covalent bonding? - CORRECT ANSWER -Non metals
What elements bond in metallic bonding? - CORRECT ANSWER -Metals
What happens during ionic bonding? - CORRECT ANSWER -
Electrons move from the outer shell of the metal to the outer shell of the non metal.
What happens to the metal in ionic bonding? - CORRECT ANSWER -
It loses electrons and becomes positively charged
What happens to the non metal in ionic bonding? - CORRECT ANSWER -
It gains electrons and becomes negatively charged
Why do ionic compounds have high melting and boiling points? - CORRECT ANSWER -
The ions are arranged in a regular lattice, and held together by strong forces of attraction within this. Th
is means a lot of force is required to break them apart.
What happens during metallic bonding? - CORRECT ANSWER -
Positive metal ions are surrounded by delocalised electrons that move in between the regular layers
Why can metals conduct electricity? - CORRECT ANSWER -
The delocalised electrons can move and carry charge. This happens in all states
What are alloys? - CORRECT ANSWER -
substances made from two or more different metals mixed together
Why do alloys have different properties to metals? - CORRECT ANSWER -
They don't have regular layers so are stronger and have higher melting points
