Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
Being extremely stable. Noble gases have full valence shells.
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.
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
I don't think noble gasses have valence electrons. They are noble because all their shells are full which makes them not as reactive.
All noble gases (helium, neon, argon, krypton, xenon and radon) have completely filled valence shells (valence orbitals).
There are no unpaired electrons. All electron shells are filled; this is the reason they are called the noble gases.
They have completely filled shells, with eight valence electrons.
Yes, noble gases have full valence shells, which is why they are stable and generally do not react with other elements. Their electron configurations result in a complete octet of electrons in their outer shell.
Argon is a noble gas. All noble gases have stable outer shells with 8 valence electrons (with the exception of He, which as 2).
They have completely filled shells, with eight valence electrons (stable) and hence are inert.
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.
Not much. Noble gases have full valence shells, or full outermost shells, so they don't tend to bond with many other elements. They are also the most stable of all the element families.
