What is it called when an electron has 8 electrons in its outer shell?
when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
Do noble gases have a maximum number of electrons in their outer energy level?
Yes they do, because, for example, neon has 2 electrons in its inner shell and 8 on its outer shell; these shells are both full. Helium, the lightest of the noble gases, has only 2 electrons, but that completes it only shell. All the other noble gases have 8 electrons in their outer shell, which is a stable arrangement.
Why helium has 2 electrons inspite of being a noble gas?
The innermost shell contains a maximum of 2 electrons, therefore like the other noble gases, it has a full outer shell. The other noble gases all have eight in their outer shells.
What is the outer shell of the noble gases called?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
Do noble gases have full outer shell of electrons?
Yes they have completely filled orbitals.

Why do noble gases not normally form compounds?
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.

Why are noble gas nonreactive?
Having the outer shell of electrons filled noble gases are very stable.
Do all noble gases have the same number of electrons in their outer shell?
Yes they all have 8 electrons in the outer shell, with the exception of Helium which has only 2.
Do noble gases have full outer shell of electrons?
Yes they have completely filled orbitals.
Noble gases have how many electrons in their outer shells?
They have 8 electrons on the outermost shell, also known as valence.
Does oxygen react with noble gases?
No! oxygen does not react with a noble gas because a noble gas does not want any electrons. This means, it's outer shell or valence shell is filled with electrons.
Which atoms have twin electrons in the first shell and eight electrons in the second shell?
Neon, plus the other noble gasses, but these other noble gases also have additional electrons in outer shells.
What is the most important property of the noble gases?
All contain a full outer shell of electrons
