Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
Now californium is considered as the heaviest naturally occurring chemical element.
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
There are 94 naturally occurring chemical elements in the universe. These elements range from hydrogen, the most abundant, to uranium, the heaviest naturally occurring element.
It depends on what you mean by 'simple'. If you mean naturally occurring then 92 as Plutonium-244 is the heaviest naturally occurring element. Any over this are synthetic. however i don't know what you mean by 'simple'
Uranium is the heaviest naturally occurring atom because it has the largest number of protons and neutrons in its nucleus compared to other naturally occurring elements. Its atomic number is 92, with an atomic mass of around 238 atomic mass units.
Uranium is the heaviest naturally occurring actinide.
No, the three densest elements under ordinary conditions are osmium, iridium and platinum, in that order. Please see the link. *************************** However, mercury is the densest liquid at room temperature.
Now californium is considered as the heaviest naturally occurring chemical element.
The heaviest element in the periodic table (known in March 2013) is ununoctium.
Osmium is the densest naturally occurring element and it is often considered the heaviest naturally occurring solid substance. However, man-made substances like depleted uranium can be even denser.
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.
The heviest element is mercury. It is heavy because it is so dense.
The heaviest (hevest?) naturally occurring element is Uranium (238 a.m.u.) but the heaviest known element is atom number 114, 117 or 118, the exact mass being unknown but over 250.

If you are talking about element sin the periodic table, it is ununoctium(Uuo)
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
