Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
How many electrons are present in an inert element or noble gases like neon?
Neon and other noble gases have a full outer electron shell, so they have 8 electrons (except helium, which has 2) due to their stable electron configuration. This full outer shell makes them highly stable and unreactive.
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 difference between noble gas and full outer shell?
A noble gas is an element found in group 18 of the periodic table that has a full outer shell of electrons, making it stable and unreactive. A full outer shell refers to an atom having achieved an electron configuration where its outermost energy level is completely filled with electrons. While all noble gases have a full outer shell, not all elements with a full outer shell are noble gases.
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 element is the only noble gas that does not have eight electrons in its outer shell?
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.

Neon and other noble gases have a full outer electron shell, so they have 8 electrons (except helium, which has 2) due to their stable electron configuration. This full outer shell makes them highly stable and unreactive.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
How valence electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
An element is stable with eight electrons in its?
Oxygen (O) has 8 protons and 8 electrons.
What is special about the electron configurations of all noble gasses?
The electron configuration of the noble gasses are such that the valence shell (the outer most shell of electrons) is filled up with eight electrons. the outermost shell of electrons can only fit eight and the noble gasses already have all eight.
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.
What is the electron configuration of the element radon?
Radon is a noble gas; it has 8 electrons in its outer shell.
Which noble gas can bond?
Noble gases typically do not form bonds because they have a full valence shell of electrons, making them stable and non-reactive. However, under certain extreme conditions, such as high pressure and temperature, it is theoretically possible for noble gases to form compounds with other elements. Among the noble gases, xenon is the most likely to form chemical bonds due to its larger size and greater flexibility in electron configurations.
What kind of gas is argon?
Argon is a Noble gas--one with eight electrons in its outer shell.
How many electrons are in argon the element?
All noble gasses have 8 valence electrons which means outer electrons. As for electrons overall, argon would have 18.
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.
