Radon is the most heaviest naturally radioactive what?
Radon is one of the noble (inert gases), is radioactive (half-life of about 4 days, decaying to polonium), and is naturally occurring in relatively small quantities. Whether or not it is the heaviest of this group, I am not sure...perhaps someone else can verify.
How many chemical elements occur naturaly in the universe?
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.
Why is uranium the heaviest atom?
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.
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
Who what is the heaviest of the naturally occurring noble gases?
Radon is the name of the heaviest noble gas.

Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.

Uranium
Who what is the heaviest of the naturally occurring noble gases?
Radon is the name of the heaviest noble gas.
What is the heaviest element known to exist naturally on earth in quantities detectable by physical test methods?
It seems to be Californium, element #98. From Wikipedia, article on "Periodic table": The elements discovered initially by synthesis and later in nature are technetium (Z=43), promethium (61), astatine (85), francium (87), neptunium (93), plutonium (94), americium (95), curium (96), berkelium (97) and californium (98).
What is the heaviest naturally element?
Either osmium or iridium. The densities are very close.
Is mercury the heaviest naturally occurring element?
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.
What is the heaviest naturally occurring metal on Earth magnesium or radium or plutonium?
Radium: Plutonium does not occur naturally, and magnesium has a low density for a metal.
What solid weighs the most?
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.
