Question

name a metal which is lighter than water​

Answer 1

Answer:

The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. ... Potassium has a density of 0.862 g/cm3 while sodium has a density of 0.971 g/cm3.
