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.
What else can I help you with?
What is The element that has no unpaired electrons in the outer shell in its ground state is?
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
How many number of electrons in the outer shell of xenon?
Xenon has 8 electrons in its outer shell. It belongs to Group 18 of the periodic table, known as the noble gases, which have full outer electron shells.
Elements with complete outer shells?
Elements with complete outer shells have a full valence shell of electrons and are stable. This configuration is typically achieved by having eight electrons in the outer shell (known as the octet rule) or two electrons for the first shell. These elements are generally inert or have low reactivity due to their stable electron configuration.
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.
How many electrons are in the outer shell of neon?
Neon is a noble gas, which means all it's electrons shells are full. innermost shell has space for 2 electrons, followed by 8 in the next shell, 8 in the next shell and so on. Answer therefore is 2.
Noble gases have how many electrons in their outer shells?
They have 8 electrons on the outermost shell, also known as valence.
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.
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.

These elements are generally inert or have low reactivity due to their stable electron configuration.
How many valence electrons are present in noble gases?
Noble gases do not like giving up electrons. There are 2 electrons in the outer shell of helium and 8 electrons in the outer shell of the other noble gases (group 18 of the periodic table), representing filled shells.
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.
Do noble gases have the maximum number of electrons in there outer energy level?
yes they do, because neon has 2 in its inner shell and 8 on its outer shell which are both full shells.
Why is helium an exception to the noble gases?
A Noble Gas does not need to have eight electrons to be classed as such - it simply must have a full outer shell. The first shell can only hold two electrons, which is what helium has, so helium is a Noble Gas. The second and third shells hold eight electrons, which is why other noble gases can be seen as having eight electrons. However no Noble Gases have eight electrons in total - just eight in the outer shell, as the shells fill from the inside out...
How many electrons are in the outer shell of neon?
Neon is a noble gas, which means all it's electrons shells are full. innermost shell has space for 2 electrons, followed by 8 in the next shell, 8 in the next shell and so on. Answer therefore is 2.
