Bismuth (Bi) is the heaviest nonradioactive element but the next heaviest is Lead (Pb) and that is much more commonly used.
The heaviest element that is naturally occurring, and also usable, though radioactive, is Uranium (U).
The heaviest alkaline-earth metal is radium. Radium is a highly radioactive element and is the heaviest and most unstable of the alkaline-earth metals.
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
Barium is the second heaviest alkaline earth metal, following radium in terms of atomic weight.
The heaviest alkaline earth metal is radium, with a molar mass of 226. If you're referring to the largest quantity in nature, it's usually calcium, due to its abundance and the fact that radium is radioactive and occurs in much smaller amounts.
The heaviest element in the periodic table (known in March 2013) is ununoctium.
Osmium oh-s-me-umm
Osmium has the highest density among metals so is heaviest metal.
The heaviest alkaline-earth metal is radium. Radium is a highly radioactive element and is the heaviest and most unstable of the alkaline-earth metals.
through my knowledge osimum is the heaviest metal
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
By density, osmium is the heaviest (22.61 kgL-1). By atomic weight, ununpentium is the heaviest (228gmol-1)
Osmium
Neon
Barium is the second heaviest alkaline earth metal, following radium in terms of atomic weight.
While francium is technically the heaviest metal in terms of atomic weight due to its higher atomic number, it is not commonly found in nature. Cesium, on the other hand, is more readily available and easier to measure. This is why cesium is often referred to as the heaviest metal.
We often hear that gold is the heaviest metal, but is this really true? In reality, the answer to this question depends on the density of each metal. Iron, gold, copper and silver all have different densities which makes it difficult to determine which one is the heaviest.
You can't change an element into another element, but the heaviest metal is tungsten.
