Question

Name two metals that start floating after sometime when immersed in water and explain why they do so.

Answer 1

calcium and sodium are two metals that start after sometimes when immersed in water

Answer 2

here is the answer.......
calcium and lithium .

this is because when calcium is immersed in water it reacts with water .
which forms calcium hydroxide.
and releases the hydrogen. hydrogen sticks at calcium which when we see appears the calcium yo float.

lithium floats on water due to density.
lithium has less density than the water .
so it can easily float on water.
