aluminum is the lightest atomic #13 titanium atomic #22 silver atomic #47 gold is heaviest atomic #79
Lithium is the lightest.
To a large extent, MAGNESIUM, element 12, is the lightest usable metal. Lithium (elmt. 3) and sodium (elmt. 11) are far too reactive to be used universally, and beryllium (elmt. 4) is very toxic and carcinogenic, thus magnesium is the lightest one that can actually be used. When powdered or shaved into small strips, magnesium is easily flammable, so in small quantities, ALUMINUM, element 13, is the lightest. But in bulk form, magnesium is surprisingly difficult to ignite, thus it is actually quite usable. Magnesium has many attractive properties. The first is the answer to the question: it's light. The second is that it is strong, especially when alloyed with aluminum or titanium (elmt. 22). It is also very abundant in the Earth's crust (9th most abundant element). Last, but definitely not least, is that magnesium is not toxic. So the answer to your question is largely magnesium, but could also be argued aluminum.
metal
Silver is the best conducting metal, both thermally and electrically. It is followed by Copper, then Gold, then Aluminum.
Titanium is a metallic element and as such does conduct both heat and electricity, but not very well, as compared to Copper, Iron, Aluminum, etc.
Aluminum is actually lighter than titanium
Aluminum, Steel, Magnesium, Stainless Steel, Titanium, Gold, Silver
Aluminum is a metal for one thing, but yes, the density of aluminum is far less than lets say, Steel.
Aluminum
Lithium is the lightest metal, Potassium is the second lightest -- density about 0.86 kg/L
aluminum, copper, titanium
Titanium and aluminum alloys
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.
