the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable

What are the main group group elements?
the noble gases
What is the main characteristic of family 18 elements?
The lowest chemical reactivity of all elements is the main chemical characteristic. An important physical characteristic is that they are all gases at standard temperature and pressure.
Why are noble gas called inert gas?
Nitrogen is typically inert for most common uses. Only the noble gases (8A) are truly inert, though they are rare. Nitrogen is a diatomic in natural state, meaning that two nitrogen atoms are stuck together. This configuration gives both atoms enough electrons to fulfill the octet. In order to get the nitrogen to react with anything the bond must be broken. Since reaction (usually) happen spontaneously when a lower energy state results, it is unlikely for the nitrogen to break on its own.
Why were the noble gases the last elements to be discovered?
They do not exist in a stable natural state. They had to be made by man in the same way as many of the Actinides This is wrong. Unlike most actinides, they all exist as stable isotopes and some are reasonably common. The main reason is that they are very chemically similar to one another and thus are hard to isolate as pure elements. this is rite...
Why does the Fe does not belong in the noble gases?
there are a lot of reasons, i think the main one is because it doesn't have a stable valence shell. my fave reason is because iron ain't a gas

What are the three main features of noble gas?
They are all unreactive They are all gases They are all monatomic
How do the physical and chemical properties of the haogens compare with those of the noble gases?
noble gases really are just that: noble. they dont react to things easily. halogens on the other hand, do react extremely easily. that is one of the main differences between the two.
What are the common gases in the galaxy?
Hydrogen and helium are the two main gases in the Universe.
What do solids and gases have in common?
Solids and gases have a number of things in common. The main similarity between the two is that they can be converted into liquid state.

What are the main gases in the atmosphere of earth?
This is the approximate composition of the atmosphere today:78% Nitrogen21% Oxygen0.004% CO2The rest consists of Noble Gases, as well as traces of other various gases, like Ammonia and Carbon Monoxide.
