Name two metals in each of the following cases:
$(i)$ Metals that are stored in kerosene.
$(ii)$ Metals that are alloyed with iron to make stainless steel.
$(iii)$ Metals which are highly malleable and ductile.
$(i)$ Metals that are stored in kerosene.
$(ii)$ Metals that are alloyed with iron to make stainless steel.
$(iii)$ Metals which are highly malleable and ductile.
(N/A) $(i)$ Sodium $(Na)$ and potassium $(K)$ are highly reactive metals that react vigorously with moisture and oxygen in the air,so they are stored in kerosene to prevent reaction.
$(ii)$ Nickel $(Ni)$ and chromium $(Cr)$ are added to iron $(Fe)$ to produce stainless steel,which is resistant to corrosion.
$(iii)$ Gold $(Au)$ and silver $(Ag)$ are the most malleable and ductile metals,allowing them to be beaten into thin sheets and drawn into thin wires.
