Which element has the lowest density among the metals?
Quick Answer
Lithium is the lightest metal, with a density of about 0.534 g/cm³.
The Full Story
Lithium is the lightest metal and has a density of about 0.534 grams per cubic centimetre, so it is less dense than water. It was discovered in 1817 by Johan August Arfwedson and is the first element in the alkali metal group. Lithium’s low density and high electrochemical potential make it crucial for rechargeable batteries. It is also used in some alloys, medicines, and high-temperature lubricants.
