Q1. Which metal is most reactive ?
Potassium reacts violently with water –
even bursting into flames.
D. Potassium
Q2. Which metal is least reactive ?
Gold is very unreactive. This
explains why gold coins can be dug up
or found in shipwrecks after
centuries.
B. gold
Q3. Which metal reacts slowly with water?
Iron goes rusty. The formation of rust is actually a reaction
between iron, water and oxygen.
C. iron
Q4. Which metal would explode in acid ?
Potassium is very reactive. It reacts
with just water – so it is possible that it will
explode with acid.
D. potassium
Q5. Which metal is at the bottom of the reactivity series?
Gold is very unreactive so it is at
the bottom of the reactivity series
B. gold
Q6. Which metal in the list is just below lithium in the reactivity series ?
Iron reacts with water but it does not do so as
quickly as lithium. So it is below lithium in the
reactivity series.
C. iron
Q7. Which metal is used for water pipes because it is unreactive?
Copper does not react with water so it is used in water pipes. (Lead used
to be used but it was found to make the water
slightly poisonous)
A. copper
Q8. Which metal is NOT in the centre of the Periodic Table?
Potassium is an alkali metal and these are
on the left of the Periodic Table.
D. potassium
Q9. Which metal is most likely to be found in a compound, not as an element?
A reactive element is always trying to make
compounds. So, potassium is very unlikely
to be found as an element.
D. potassium
Q10. Which metal could you safely use to displace copper from copper sulphate?
Iron is above copper in the reactivity series so it will displace it from copper
sulphate. Potassium would also displace the copper -
but this would not be a safe reaction to try !
C. iron
