There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.

Which group has a complete outermost shell in a periodic table?
group 18, noble gases
Which family does not easily combine with other atoms?
Noble gases does not easily combine with other elementsbecause they are stable and have complete outermost shell.
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.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
What is the main characteristic that all the noble gases have in common?
the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
Which group has a complete outermost shell in a periodic table?
group 18, noble gases
Which is the noble gases does not posses 8 electronS in its outermost shell?
it is Helium.
Which family does not easily combine with other atoms?
Noble gases does not easily combine with other elementsbecause they are stable and have complete outermost shell.
Is O a molecule?
O is the symbol for Oxygen, which is not a noble gas.No, Oxygen (O) is in group 6 and the noble gases (or inert gases) are in group 8.oxygen is not a noble gas because in order to become a noble gas it is necessary to have a completely filled outermost shell. as oxygen has only 6 electrons in its outermost shell it is not a noble gas because noble gases have 8 electrons which completely fill the outermost shell
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.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
What element has 8 electrons in 1 atom?
These are the Noble gases which are generally inert. (Except for Helium, which has two electrons, but which is still considered a Noble Gas.)
What group of elements have an outermost electron shell that is complete?
Inert gases
What is the main characteristic that all the noble gases have in common?
the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
How many electrons are found in the outer lever of all the noble gases except helium?
2 electrons are found in the outermost electron shell of Helium. 8 electrons are found in the outermost electron shell of all other noble/inert gases.
Has Eight electrons in a valence shell?
These are the noble gases which have a complete valence shell.
Do noble gases have a full octet of electrons?
If by octect you mean the outermost shell, then yes.. that's why they're noble gasses (inert)
