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 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 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.
How many electrons do the elements of the most stable group have in their outer shells?
Most of the noble gases have 8 electrons in their outer shell, but helium has only 2, and is the most stable of all elements.
What 3 elements on the periodic table had complete outer shells?
All the Noble/Inert gasses. However, Helium (He) has a complete outer shell of only TWO(2) electrons. The other noble gases all have a complete octet (outer) shall, of EIGHT(8) (Octet) electrons.
When is the valence shell stable?
Whenever the outside shell of the atom, or valence shell, is completely full with electrons. Ex: The noble gases are lucky enough to start out stable because they fill their outer shells.
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.
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 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.
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.
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.
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 do the elements of the most stable group have in their outer shells?
Most of the noble gases have 8 electrons in their outer shell, but helium has only 2, and is the most stable of all elements.
What is the link between noble gas and full outer shells?
Noble gases have completely filled valence electrons. Helium has 2, other elements have 8
What 3 elements on the periodic table had complete outer shells?
All the Noble/Inert gasses. However, Helium (He) has a complete outer shell of only TWO(2) electrons. The other noble gases all have a complete octet (outer) shall, of EIGHT(8) (Octet) electrons.
