A noble gas element has as many valence electrons as are needed to completely fill its valence shell: 2 for helium and 8 for all the others. Since a filled valence shell is the condition that other atoms are most likely to reach during chemical reaction, the noble gases are unreactive except with extremely electronegative elements such as fluorine, for which the chemical driving force for gaining an electron to fill the fluorine valence shell is stronger than the energy input required to extract an electron from one of the heavier noble gas atoms.

How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
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.
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
What is odd element in noble gases?
The odd element in the noble gases is Radon. This is because it is radioactive, and all the others are highly unreactive.
Why are noble gases stable and unreactive?
Noble gases are stable because they have a complete outer shell - that is, eight valence electrons. Other elements react in order to gain or lose valence electrons, but noble gases are satisfied.
Why is chlorine very reactive and argon is unreactive?
Chlorine needs to gain (-1) one valence electron to become unreactive like Argon. The reason why Argon is unreactive is because it had 8 valence electrons.
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
Why argon is chemically unreactive?
Because it has a full complement of eight electrons in its valence shell.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
Valence electrons of helium?
Helium has two valence electrons in the 1s orbital.
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.
Why is the element xenon unreactive?
The outer electron shell of the xenon atom is full, there are no valence electrons to promote activity.
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
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).
What is odd element in noble gases?
The odd element in the noble gases is Radon. This is because it is radioactive, and all the others are highly unreactive.
Why are noble gases stable and unreactive?
Noble gases are stable because they have a complete outer shell - that is, eight valence electrons. Other elements react in order to gain or lose valence electrons, but noble gases are satisfied.
Can hydrogen fill it's outside shells with two electrons?
No. Hydrogen is extremely unreactive because it only has one valence electron.
