Question

Name two metals that start floating after some time when immersed in water and explain why they do so ?

Answer 1

Lithium and sodium float in water because of their low densities. Lithium gradually reacts and disappears, forming a colourless solution of lithium hydroxide whereas sodium (which also forms its corresponding hydroxide) melts almost at once to form a small silvery ball that dashes around the surface
