With a density of 0,534 g/cm3 lithium is the lightest between metals.
The lightest 'non-metal' could be Hydrogen and Helium! Both are gases, and therefore, not a metal.
The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.

Alluminum is probably the lightest of coinage metals used to-date.
The lightest metal element is lithium, with an atomic number of 3 and an atomic weight of around 6.94. It is also the lightest metal that is a solid at room temperature and is commonly used in batteries and other electronic devices.
Lithium is the lightest element metal with a relative atomic mass of 7 (3 protons, 4 neutrons).
Lithium is a soft white alkali metal that is the lightest metal under standard conditions. It is also the least dense solid element.
