What is the heaviest of all the elements?

Answer 1

In terms of atomic mass or density?

An element with atomic number 118 has been reported. This would be assumed to have the greatest atomic mass, but it is too short lived to measure. Element 113 has had a measused atomic mass of 282 amu.

In terms od density, perhaps Iridium (atomic number 77) with a density measured at 22.5 g/mL followed by Osmium (atomic number 76) at 22.4 g/mL.

Answer 2

In July 2001 the discovery of two new "superheavy " elements was announced by scientists at the U.S. department of Energy's Lawrence Berkely National Laboratory. Element 118 ans its immediate deacy product, element 116, were discovered at Berkley Lab's 88-inch Cyclotron by bombarding tarhets of lead waith an intense beam of high energy krypton ions. Although both new elements almost instantly decay into other elements, the sequence of decay events is consistent with theories that have long predicted an "island of stability" for nuclei with approximately 114 protons and 184 neutrons.

Answer 3

The heaviest natural element is Uranium, with an atomic mass in the 230s. Everything heavier is synthetic and highly unstable.

Answer 4

If you mean density of a natural element is Iridium, 22.650 Kg/m3.

Answer 5

Hassium by amu

Mercury by density

Answer 6

The element of surprise. see how long you can carry it

Answer 7

I know the densest is whatever is in Hugo Chavez's brain.

Answer 8

hassium
