Polonium is often considered to be the most radioactive element, but there are far more radioactive elements like nobelium and lawrencium. However, the most radioactive elements are man-made like ununtrium and ununseptium. Out of these, ununoctium is the most radioactive but scientists are continuing to make even more radioactive elements today.
What else can I help you with?
What is the heaviest element in group 16?
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive metal.
What is the heavist element in the periodic table?
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.
Which is the heaviest member of halogen family?
It is the 117th element called Ununseptium. It is artificially synthesized. So heaviest naturally occurring halogen is Astatine.
What is the 85th element on the Periodic Table of Elements?
The 85th element on the Periodic Table of Elements is astatine (At). It is a highly radioactive element and the heaviest known halogen. Astatine is rare and is primarily produced as a result of decay processes in uranium ores.
What element is the heaviest element found announced in February 2004?
The heaviest element announced in February 2004 was ununpentium with the atomic number 115.
Heaviest element that is highly radioactive?
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
Which is the heaviest radioactive element?
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.
What is the heaviest element in group 16?
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive metal.
What is the heaviest Alkaline-earth 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.
Which element has the heaviest atoms from the group calcium fluorine uranium?
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.
What is the heaviest usable metal?
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).
What are three unusual or unique facts about your element uranium?
1. Uranium is the heaviest natural chemical element. 2. Uranium is radioactive 3. Uranium isotope U-235 is fissile
Is seaborgium a metal or nonmetal?
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.
What is the heaviest non-radioactive alkali Earth metal?
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
What is the heaviest element found as a liquid?
Mercury is the heaviest element at a liquid state.
What is the heavist element in the periodic table?
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.
What is the largest natural stable element?
Bismuth Francium has the largest atom - the greatest atomic radius.
