The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
All noble gases have 8 valence electrons. Helium has only 2.
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
noble gasses are toward the right side of the periodic table the # of electrons is the group and you can find valence out by taking the group # and subtracting 10 from groups 11-18 to get the answer of 8 valence electrons
All noble gasses have 8 valence electrons which means outer electrons. As for electrons overall, argon would have 18.
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
Helium has 8 valence electrons. It is a noble gas. none = 0
normally 8
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
the neon family (the noble gases) have 8 valence electrons.
eight
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
