Just so, what are the physical properties of lithium?

Lithium is a very soft, silvery metal. It has a melting point of 180.54°C (356.97°F) and a boiling point of about 1,335°C (2,435°F). Its density is 0.534 grams per cubic centimeter. By comparison, the density of water is 1.000 grams per cubic centimeter.

What are the physical and chemical properties of lithium?

Chemical properties. In many of its properties, lithium exhibits the same characteristics as do the more common alkali metals sodium and potassium. Thus, lithium, which floats on water, is highly reactive with it and forms strong hydroxide solutions, yielding lithium hydroxide (LiOH) and hydrogen gas.
