Because the outer electron shell is full as is the case with helium and neon or because it has the stable octet configuration, with 8 electrons, which is true for the rest, argon, krypton, xenon and radon.

Are noble gases reactive or unreactive?
Unreactive
The most unreactive family of gases?
The Noble Gas group, which is Group 18.
The most characteristic property of the noble gases is that they?
Noble gasses are not reactive. :)
Most unreactive group in the piriodic table?
The noble gases are the most stable unreactive elements on the periodic table, they are helium, neon, argon, krypton, xenon, radon
What is the name of the group with most unreactive elements?
Noble gases (or group 18 elements)
Are noble gases reactive or unreactive?
Unreactive
The most unreactive family of elements?
The Noble Gases, group 18
The most unreactive family of gases?
The Noble Gas group, which is Group 18.
The most characteristic property of the noble gases is that they?
Noble gasses are not reactive. :)
Are noble gases very unreactive gases?
Correct.
Most unreactive group in the piriodic table?
The noble gases are the most stable unreactive elements on the periodic table, they are helium, neon, argon, krypton, xenon, radon
What is the name of the group with most unreactive elements?
Noble gases (or group 18 elements)
Where in the periodic table find the the most unreactive elements?
The most unreactive elements, called the noble gases, are found in the group 8 of the period table.
Why are noble gases very reactive?
Nobel gases are very unreactive.
What familyof coumpounds is most likely to be relatively unreactive?
The "Noble gases" of group VIII are unreactive, because they are stable, due to their electron arrangements. If an atom has a full outer shell, it is "happy" and will not bond with other atoms.
Explain why noble gases are unreactive in terms of electron shells?
Noble gases are unreactive because their outermost shell, the valence shell, has a full set of eight electrons.
Justify why the noble gas family is unreactive?
In short, an element's valence shell is full and most stable when it contains eight electrons (this stability is the reason that the noble gases are so unreactive).
