Why are noble gasses also known as inert gasses?
The noble gases were once called inert gases because until about 1960, no compounds of them had been discovered.
Why are noble gases also called inert gases?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements) and are known as inert gases.
The noble gases are almost completely nonreactive for this reason they are sometimes called what?
Inert gases. This was a common term for them until the first reaction between a noble gas and another material was discovered a few decades ago.
What do noble gases all have in common?
They are not very reactive and they do not form bonds with each other, so molecules of noble gases cannot be formed, there are only atoms, i.e. they are monatomic gases.. Up until 1962 no noble gas compounds were known however compounds of Argon, Krypton Xenon and Radon all form unstable compounds with fluorine.
Discoverer of the noble gases?
The noble gases were first isolated by different people at different times for example Helium - Pierre Janssen in 1868 Neon - Sir William Ramsay in 1898 Argon - Lord Rayleigh and Sir William Ramsay in 1894

What are inert gases?
Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.
What are some of argon's physical or chemical properties?
argon is a noble gas, number 18 with a mass of about 40 amu. noble gases almost never make compounds, so it's chemical property is that it is almost totally unreactive with other elements. Physically it is a gas until just about minus 200 centigrade, when it can liquify. gases have very low density. there's not much going on with noble gases, they're called noble as an insult to the nobility of the European aristocracy. The nobles never mingled with the peasants, and isolated themselves from the rest of society. Noble gases never "mingle" with peasant elements either.
Why are Nobel gases are sometimes called inert gases?
Noble gases used to be called inert gases because until the 1960's no chemical compounds of a noble gas had been made hence they were believed to be completely inert. Now compounds of argon, xenon radon have been made. These are all very reactive. Compounds of helium and neon have not yet been made.

What are noble gases and where on the periodic table are they?
Noble gases are elements that have all possible electron positions in the outer, or valence, shell filled. This makes them chemically non-reactive. They are found in group 18 on the periodic table (far right edge) of elements: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). The name ununoctium has been assigned to what would be the next element down i the column, Note that the noble gases, were originally considered to be inert until the 1960s when some creative chemists managed to find a way to get them to form some molecules with a few other elements like fluorine. Of the noble gases Xenon seems to be easiest to get to form compounds
What makes Noble gases different than any other element?
Noble gases differ from other elements in that the number of electrons that are attached to the core is exactly right. Most elements have either too much or too few electrons to fill their shells (rings of electrons surrounding the nucleus). Noble gasses therefore do not interact with other elements to shed, share or steal electrons like other elements do. Under normal conditions these gases do not react with any other element, and it is therefore that no one ever isolated a noble gas until 1895.
