<P> Lithium has a very low density ( 0.534 g / cm ) , comparable with pine wood . It is the least dense of all elements that are solids at room temperature ; the next lightest solid element ( potassium , at 0.862 g / cm ) is more than 60 % denser . Furthermore , apart from helium and hydrogen , it is less dense than any liquid element , being only two thirds as dense as liquid nitrogen ( 0.808 g / cm ) . Lithium can float on the lightest hydrocarbon oils and is one of only three metals that can float on water , the other two being sodium and potassium . </P>
