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.
Lithium is the lightest metal, Potassium is the second lightest -- density about 0.86 kg/L
The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.
Mercury is the only liquid metal. Bromine comes under group 7 in the table and is therefore a Halogen. Bare in mind that this is only true at standard states.
The lightest metal in the periodic table is lithium (Li) with atomic number 3 density 0.53 kg/L. However, the metal with the highest strength to weight ratio is titanium (Ti). Lithium metal is extremely soft (and highly reactive) and so is unusable for many applications, but one atom of Li weighs 1/7th of an atom of Ti.

Lithium is the lightest element metal with a relative atomic mass of 7 (3 protons, 4 neutrons).
Alluminum is probably the lightest of coinage metals used to-date.
Lithium is the lightest metallic element. Its atomic weight is 6.491.
Lithium is a soft white alkali metal that is the lightest metal under standard conditions. It is also the least dense solid element.
