The heaviest natural radioactive element is Uranium.
Man made elements are continuously being made. The latest heaviest superheavyweight man made element to be discovered is element 117 (it is still so new that it hasn't been given a name yet).
A little different bit of information about Fermium, a team has captured a piece of its spectrum-the wavelengths of light it absorbs-making it the heaviest element ever to be so measured. It was made in the 1952 detonation of the first thermonuclear bomb. It does not make it as the heaviest element, just the heaviest to have it's light spectrum captured.
Seaborgium is a synthetic element that belongs to the category of transition metals on the periodic table. It is a highly radioactive metal and is the heaviest element in the actinide series.
Bismuth Francium has the largest atom - the greatest atomic radius.
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
The heaviest element with a one letter atomic symbol is uranium (symbol: U).
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive 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.
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.
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).
1. Uranium is the heaviest natural chemical element. 2. Uranium is radioactive 3. Uranium isotope U-235 is fissile
Seaborgium is a synthetic element that belongs to the category of transition metals on the periodic table. It is a highly radioactive metal and is the heaviest element in the actinide series.
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
Mercury is the heaviest element at a liquid state.
The heaviest stable element is bismuth, atomic number 83, atomic weight 208.9804). Any heavier element is radioactive, which means it decays into lighter elements - uranium, the heaviest naturally occurring element, will eventually decay into lead-207.
Bismuth Francium has the largest atom - the greatest atomic radius.
