What else can I help you with?
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.
Heaviest of the noble gases?
Radon is the heaviest of the inert gases. The inert gases are also known as the noble gases and are the lightest elements.
What is the heviest noble gas?
Noble gases belong to group 0 and can be found on the extreme right column of the periodic table of elements. The heaviest noble gas would be radon, whose atomic mass is still uncertain. The element which appears below radon in the column, ununoctium, has not been confirmed as a noble gas.
Roughly how many elements are there?
90 naturally occurring elements, unknown number possible elements.
What have a full set of electrons on their outermost energy level?
The noble gases (group 18/VIIIA/0) are naturally occurring elements that have a full valence shell with eight valence electrons (an octet), except for helium which has two valence electrons (a duet). This makes these elements very stable and very nonreactive.

Why do you think the noble gases were among the last of the naturally occurring elements to be dicovered?
Noble gases are chemically inert, they do not form compounds. They are found in trace amounts and hence difficult to be identified.
Why are noble gases are among the last of the naturally occurring elements to be discovered?
Because they don't react with anything else; when you're looking for reactions, noble gasses are invisible.
What is the greatest noble gas?
It depends on what you mean by great. If you mean most massive, then radon has the biggest naturally occurring ones. ( However element 118 has been made artificially). If you mean the most common, then it is argon.
What are the noble the?
The noble gases are a group of chemical elements with similar properties. They are odorless, colorless, and have low chemical radioactivity. The 6 naturally occurring noble gases are:Helium (He)Neon (Ne)Argon (Ar)Krypton (Kr)Xenon (Xe)Radon (Rn)
What is the heaviest elemet of the noble gases?
Down the group the density generally increases. Thus radon will be the heaviest element.
Is xenon synthetic?
No, xenon is a naturally occurring chemical element that is part of the noble gases group on the periodic table. It is found in trace amounts in the Earth's atmosphere and is extracted through the process of fractional distillation of liquid air.
What is the heviest noble gas?

To what family does the element 'krypton' belong?
The noble gases is the family to which the element krypton belongs. Noble gases share such similar characteristics as an absence of color and odor and a low level of chemical reactivity. The other naturally occurring noble gases are argon, helium, neon, radon, and xenon. The word 'krypton' owes its origins to the classical Greek language of the ancient Greeks, where 'kryptos' means 'the hidden one'.
