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.
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 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.
What is true about the electron configuration of the noble gasses?
The electron configuration of noble gases is characterized by a complete outer shell of electrons, which makes them highly stable and unreactive. This full valence shell corresponds to the maximum number of electrons allowed in that shell, adhering to the octet rule for most noble gases. For example, helium has a complete outer shell with two electrons, while the other noble gases, such as neon, argon, and xenon, have eight electrons in their outer shells. This stability is the reason noble gases are found in nature in their monatomic form.
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...
Why noble gasses are not active?
Noble gases are not active because of their outer shells. The outer shells of these gases are full of 8 valence electrons, which make them stable and inert.
How many electrons do the elements of the most stable group have in their outer shells?
Elements in the most stable group of the periodic table, also known as the noble gases, have full outer shells. This means they have 2 electrons in the case of helium, and 8 electrons for all other noble gases.

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

How many valence electrons does is have argon?
Argon is a noble gas. All noble gases have stable outer shells with 8 valence electrons (with the exception of He, which as 2).
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.

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.
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.
