Uranium is a heavy chemical element, but not the heaviest; the aspect is due to a greater number of protons and neutrons.
Uranium atom is the heaviest.
The heaviest atom known today is 294Uuo, an isotope of ununoctium.
Osmium oh-s-me-umm
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
URANIUM (:
Uranium atom is the heaviest.
The largest. Uranium and the trans-uranium atoms are the most massive.
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
Uranium is the heaviest naturally occurring actinide.
The heaviest element with a one letter atomic symbol is uranium (symbol: U).
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.
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.
The heaviest atom known today is 294Uuo, an isotope of ununoctium.
