This element is ununoctium - atomic number 118.
Ununoctium - atomic number 118.
The heaviest man-made element is Oganesson (Og), with an atomic number of 118. It is a synthetic element that was first synthesized in 2002 by Russian and American scientists. Oganesson is highly unstable and has a very short half-life, making it difficult to study.
I believe it is Uranium. All elements heavier than uranium are man-made. Here's an interesting article... http://space.newscientist.com/article/dn13828-has-the-heaviest-element-been-found.html
The information in the question 'What is the heaviest element?' should answer this. Access this by the web link below.
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.
I think this is a trick question. The heaviest NATURAL element is Uranium (#92) but there are several heavier man-made ones. Every couple of years they are able to make another heavier one and IT becomes the heaviest. So I think the answer should be "there is no HEAVIEST element in the periodic table - it keeps changing."
Iron is an element, and is the heaviest element that may be made by fusion in a Star such as our Sun.
This element is ununoctium (Uuo): atomic number 118.
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.
Mercury is the heaviest element at a liquid state.
Did you know that this element is the heaviest ever made?
The heaviest natural element is Uranium (number 92). There are made heavier elements (I think the heaviest is ununheksium, number 116), but these atoms only live in less than a second before they split into smaller atoms.
