What are five elements that are noble gases?
I think it would be easier to say what gases ARE noble gases. The six noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. Any other elements are not Noble gases. This can include elements like Gold, Mercury, Calcium, Potassium, and barium.
What element is not found in most organic compounds?
Uranium. Also fluorine, lead, any of the noble gases, all the lanthanides, gold, silver, copper...
Why are Group 8A elements known as noble gases?
The grup 8 elemnts are quite unreactive- the term noble was I think coined for gold and other unreactive metals- and the adjective got re-used- they were once called the inert gases- but this is no longer true as unstable reactive compounds have been made for Argon and the heavier members of the group.
Are the least reactive metals easier to extract?
NO Gold and platinum are not revy reactive.
What group in the periodic table is the most inert?
As far as "inert gases" (noble gases), the heaviest is the radioactive gas radon (atomic number 86, only natural isotope 222Ra).Referring to "inert" precious metals, the heaviest is gold (atomic number 79). Precious metals are not non-reactive and may either oxidize or dissolve in acids.

Is Gold chemically active or inert?
Gold is active, or at least not inert. Only the noble gases are inert.
Why does gold have highly resistant?
Noble metals have chemical similarity to noble gases, so they are resistant. Gold and platinum are the hardest to oxidize, by the highest potentials in electromotive series
What are the only elements that exist in nature as in uncombined atoms?
The noble gases, gold and platinum.
Which group of elements is very stable and nonreactive?
The class of noble gases (Helium, Neon etc. in group 18) There are two groups that come to mind when talking stability: the noble gases and the coinage metals. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are very chemically stable and do not readily form compounds. Note that although Radon is chemically stable, it's not stable from a nuclear standpoint and will decay (but it is not reactive in the chemical sense). The coinage metals (such as gold, silver, and copper) are very unreactive. Note that the further an element is from Au on the periodic table, the more reactive it is (obviously the Noble gases do not follow this trend).
What element is not found in most organic compounds?
Uranium. Also fluorine, lead, any of the noble gases, all the lanthanides, gold, silver, copper...
Which element shows little reactivity?
Examples are noble gases and metals from the platinum group.
What are noble gases and why it is called do?
In mediaeval times metals like gold and platinum were called "noble metals" because they "were not subject to corruption", that is, they did not tarnish nor rust. When William Ramsay and co-workers discovered five group 18 elements at the end of the 19th century, they were known as the "inert gases" because they were unreactive, or as the "noble gases" by analogy with the very unreactive metals. After compounds of xenon were discovered in the 1960s, the former name dropped off, and since then they have been known as the "noble gases"

Why is gold considered to be a noble metal though it has only one electron in the valence shell?
In chemistry terms, 'noble' is often applied to describe the inert gases of the 8th group in the periodic table. When applied to gold, it is used in the normal sense; noble meaning 'of a higher station or rank of importance', because of its low reactivity.
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
What are the only elements that are distinct in nature as uncombined atoms?
The noble gases generally exist in nature in monoatomic form. Some metals are unreactive enough to exist in nature as pure "nuggets" of metal; gold is probably the most notable, but there are places where one can find nuggets of (nearly) pure copper as well.
