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 electrons does the heaviest naturally occurring element have?
The heaviest naturally occurring element is uranium, and it has 92 electrons.
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).
Who what is the heaviest of the naturally occurring noble gases?
Radon is the name of the heaviest noble gas.
Why is uranium the heaviest atom?
Uranium is a heavy chemical element, but not the heaviest; the aspect is due to a greater number of protons and neutrons.

Radon is the name of the heaviest noble gas.
What is the heaviest usable metal?
Bismuth (Bi) is the heaviest nonradioactive element but the next heaviest is Lead (Pb) and that is much more commonly used. The heaviest element that is naturally occurring, and also usable, though radioactive, is Uranium (U).
What is the heaviest naturally element?
Either osmium or iridium. The densities are very close.
Why is uranium the heaviest atom?
Uranium is a heavy chemical element, but not the heaviest; the aspect is due to a greater number of protons and neutrons.
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.
Which largest bird is naturally found in Australia?
The tallest bird in Australia is the emu, but the heaviest bird is the Southern cassowary.
Which is the heaviest member of halogen family?
It is the 117th element called Ununseptium. It is artificially synthesized. So heaviest naturally occurring halogen is Astatine.
