It is about Cf element. it is in the !8th group.
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive metal.
The heaviest element announced in February 2004 was ununpentium with the atomic number 115.
Now californium is considered as the heaviest naturally occurring chemical element.
Jazz, who was a member of Dru Hill, was the heaviest member of the group.
It is the 117th element called Ununseptium. It is artificially synthesized. So heaviest naturally occurring halogen is Astatine.
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive metal.
This element is francium.
Down the group the density generally increases. Thus radon will be the heaviest element.
Barium is the heaviest element in the group 2 after Radium. Chemical symbol for barium is Ba. Atomic number of it is 56.
Uranium has the heaviest atoms out of these three elements. It is a radioactive element with atomic number 92 and a relatively high atomic mass.
Mercury is the heaviest element at a liquid state.
The heaviest radioactively stable element in the same column of a wide form periodic table as nitrogen is bismuth.
The heaviest element in the periodic table (known in March 2013) is ununoctium.
Ununhexium is the heaviest metal in the periodic table of elements. It is man made however, so it might not count. The heaviest natural metal might be Radium.
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
