Metal which floats on water
WebAnswer (1 of 2): 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. Two other metallic elements are less dense tha... WebAn object will float if its average density is less than the average density of the fluid it is immersed in. But you might ask, how can a cruise ship, which is constructed of metals weighing thousands of kilograms, float on water if all those dense metals have a higher average density than water?
