最重的金属应该是指密度最大的金属。答案应该是锇，锇(符号为Os)的密度约为 22.59 g/cm^3 而铀的密度只有 19.1 g/cm^3而「锇是银白色的过渡金属，是常温常压下密度最大的元素。锇可在铂矿中发现。锇可添加到合金中，例如钢笔笔尖、电子开关等需要高硬度及耐用性的地方。锇在空气中可被氧化成易挥发且有 *** 性的四氧化锇固体，此物对人眼伤害很大，锇的拉丁文名正是由它而来（名字的意思是「恶臭」）。」以上资料来自 *** 若以单一金属元素质量最大，则很难有答案，因为不断有新元素发现，例如��、䥑、钽、錀、鎶的质量亦比铀大。
Plutonium (Pu) 钸 is the heaviest metal. Atomic Number 94
Density 19.84 g/cc (Compare to Uranium
Atomic number 92
density 19.05 g/cc) Plutonium is usually man-made
but it can be found in trace amount in natural uranium ores. Colour: silvery-white
世界上最重既物料系咩?? 1)金属之中最重 Uranium (铀). It is the heaviest naturally occurring element
with an atomic number of 92. Uranium is nearly ice as dense as lead. 2)系边度见到 Uranium occurs in most rocks in concentrations of 2 to 4 parts per million
and in much lower concentrations in seawate. 3)外貌 Uranium in its pure form is a silver-colored heavy metal.
