is the heaviest element currently on the periodic table, weighing in with a huge atomic mass of about 300. Only a few atoms of the synthetic element have ever been created, each of which survived for less than a millisecond.

One has to hike to see it -- a design plan Wright felt would heighten the excitement and retain the sense of awe one would feel upon making the effort to view the cascade. Wright visited the future site of the Kaufmann's vacation home twice in the more than year-long span between...
At present, 118 elements are known to us. All these have different properties. Out of these 118, only 94 are naturally occurring.
The cuts created using the Knife tool appear as strokes on the object. Select the anchor point where you want to split the path, and then click the Cut Path At Selected Anchor Points button in the Control panel. When you split the path at an anchor point, a new anchor point appears ...
The five heaviest buildings ever moved rank high in the history of structural moving. Learn what those five heaviest buildings are.
The lightest chemical elements, including hydrogen, helium and smaller amounts of lithium, beryllium and boron, are thought to have been produced by various cosmic processes during the Big Bang and cosmic-ray spallation. Production of heavier elements, from carbon to the very heaviest elements, ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
Iron is also found in the cores of all of the planets in the Solar System. Iron is the heaviest element formed in the cores of stars, according to JPL. Elements heavier than iron can only be created when high mass stars explode (supernovae). The Latin name for iron is ferrum, which...
000 feet long, 300 feet wide and 60 feet deep -- big enough to construct the six concrete sections that would make up the tunnel. The longest of the six tunnel sections was 414 feet long, the widest 174 feet wide. All were about 27 feet high. The heaviest weighed more than 50,000 ...
