#1
Front (Question)
Describe the structure of a metal lattice
Back (Answer)
Positive metal ions surrounded by delocalised electrons
#2
Front (Question)
Metallic bond
Back (Answer)
Electrostatic attraction between positive metal ions and delocalised electrons
#3
Front (Question)
Displacement reaction
Back (Answer)
A reaction in which a more reactive metal displaces a less reactive metal from a compound. E.g. Mg + FeSO4 → MgSO4 + Fe
#4
Front (Question)
What allows metals to conduct electricity?
Back (Answer)
Delocalised electrons (charged particles + free to move)
#5
Front (Question)
Why must a d.c. supply be used during electrolysis?
Back (Answer)
So that the products can be identified. Otherwise, a mix of products is made at each electrode
