Why did it take scientists so long to discover the noble gases?

and because they were quite stupid

∙ 13y agoNoble gases are furthest right on the Periodic Table of elements so their outer valence electrons fill each level, making it stable
the elements don't want to react because they are stable, and it would take energy to change/move electrons, creating ions, so it is unnecessary and therefore rare for the noble gases to react.

∙ 13y agoNoble gas are also known as inert gas, b'coz they are less or we may say unreactive. It is b'coz they have fully filled electrons in their valence shell. However, xenon is slightly reactive. It resembles oxygen in some properties. Valence shell is responsible in defining reactivity as it took part at the time of bond formation. Now, let us take electronic configuration of ny1 noble gas say neon(Ne), i.e., 2s^ 2p^6, which reveals that it has filled valence shell. Remembr, the electronic configuration of noble gases r ns^2 np^6. Hope this will help.

∙ 10y ago- noble gases are very rare (excepting argon)
- noble gases are practically unreactive: the haven't compounds in the nature
Wiki User
∙ 11y agoBecause noble gases are colorless and odorless and non-reactive.
Wiki User
∙ 15y agoBecause they are generally very small and usually won't bond with any other elements because all there outer shells of electrons are full so no bonding will accour.
Wiki User
∙ 14y agoIt took a long time to discover the noble gases because they do not react in basic reactions.
Wiki User
∙ 10y agoThey are very rare (excepting argon) and also they are inert gases.
Wiki User
∙ 9y agoThey do not chemically react, so they could only be separated by physical means. The method used to separate them is fractional liquefaction.

Is it appropriate to refer to group viii elements as inert gases?
As long as you're referring to the rightmost group (starting with Helium) then yes, they are referred to as Noble/Inert gases.Note: Many scientists will call it group 18 instead of group 8.
Which property is common to noble gases brightly colored strong odor low reactivity high reactivity?
Noble gases are present in group 18 on the modern periodic table. Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Why wont hydrogen bond with other noble gases?
First - Hydrogen isn't a noble gas.Actually, no elements will bond with noble gases except under extreme conditions. Chemicals bond by either sharing or trading electrons. Noble gases have all of the electrons they need, and hydrogen atoms have one extra electron, thus noble gases don't want to bond.In 1933 Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. Specifically, he predicted the existence of krypton hexafluoride (KrF6) and xenon hexafluoride (XeF6), speculated that XeF8 might exist as an unstable compound, and suggested that xenic acid would form perxenate salts. These predictions proved quite accurate, although subsequent predictions for XeF8 indicated that it would be not only thermodynamically unstable, but kinematically unstable. As an example of the extreme conditions usually required to make such molecules, Xenon hexafluoride can be prepared by long-term heating of XeF2 at about 300°C and pressure 6 MPa (60 atmospheres).
Sources of noble gases?
The noble gases are rather uncommon on Earth. Collectively, they make up about 1 percent of Earth's atmosphere. Most of the noble gases have been detected in small amounts in minerals found in Earth's crust and in meteorites. They are thought to have been released into the atmosphere long ago as by-products of the decay of radioactive elements in Earth's crust. (Radioactivity is the property that some elements have of spontaneously giving off energy in the form of particles or waves when their nuclei disintegrate.)
How did scientists able to draw conclusions about how long El Nino has been affecting the weather?
they just do it cause they are scientists

How did scientists discover mountains?
Mountains are quite big so they are rather hard to miss. People knew about mountains long before there were any scientists.
How long after Hooke discovered cells did scientists discover that life is made of cells?
Not until the mid-to-late 1800s
Will scientists discover new dinosaurs?
Paleontologists are constantly discovering new dinosaurs. This will probably continue for a very long time to come.

How long does it take for a fart to travel a mile?
Body gases can travel at quite speeds, but this is not necessary to know and therefore scientists would rather spend their time on something else.

How does Long John Silver act noble?
The truth is that Long John Silver is NOT noble. in fact he is selfish and greedy!
why did it take scientists so long to discover chemosynthesis?
Chemosynthesis was first identified in 1977 when a team of scientists on an ocean research expedition near the Galápagos Islands off the coast of Ecuador found hot vents on the ocean floor spewing a chemical soup of hot fluid.
How do you spell gases?
gases! you spelled it! as long as you mean gas as in air... :)
What is the county of origin for the surname Long?
The proud and noble English Long family name descends from a Norman noble of Preux in Normandy.
How did scientists find out that you don't use all the oxygen you breathe in?
Even before they had names for the gases in air they played games with candles. Exhaust breath will allow a candle to burn, but not as long as fresh air.
