How many electrons does it take to fill the outer shell to become like a noble gas?

For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).

What is the difference between noble gas and full outer shell?
Noble gases or the inert gases as they are become know as have a full outer shell. It is possible to get different elements to fill in the last outer shell but it is extremely difficult to take electrons from a noble gas therefore when you ask what the difference is the question is perhaps not phrased properly because there is no difference they are two different categories. A noble gas is an element with a full outer shell and full outer shell is when an element has filled all of the max electrons in the last orbital.
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.
Which noble gas can bond?
No noble gas will bond in an unexcited state. All noble gases have a complete outer valence shell consisting of eight electrons. (Helium excluded- whose outer electron shell is completed with two electrons)
How many electrons does noble gases have in the outer shell?
8 electrons (except for helium which has 2)
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.
Why some atom lose or gain electrons to become ions but noble gas atom never become ion?
Noble gases have a very stable structure, the outer shell of electrons is full.
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.

How many electrons are in the outer shell of Ar?
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
Do noble shells have a full outer shell of electrons?
Every noble gas does have an outer shell. That's why they don't want to react with any other element. This is because they don't want to gain or lose any electrons. Because they have a full outer shell.
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.

No noble gas will bond in an unexcited state. All noble gases have a complete outer valence shell consisting of eight electrons. (Helium excluded- whose outer electron shell is completed with two electrons)

What element is the only noble gas that does not have eight electrons in its outer shell?
it is helium He. it has 2 electrons
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.
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.
