ANSWER
1-5 Aluminium is a metal.
Describe how metals conduct electricity. Answer in terms of electrons.
[3 marks]
ANSWER
Aluminium is a metal with delocalized electrons which carry electrical charge (i.e. electrons move) through the metal / aluminium / structure.
1-6 Name the type of bonding in compounds formed between metals and non-metals
[1 mark]
ANSWER
Ionic bond
Magnesium oxide is a compound formed from the metal magnesium and the non-metal oxygen.
Describe what happens when a magnesium atom reacts with an oxygen atom. You should refer to electrons in your answer.
[4 marks]
ANSWER
Magnesium atom loses electrons and oxygen atom gains electrons two electrons and hence magnesium ions and oxide ions are formed.
