What else can I help you with?
Why don't noble gases normally form chemical bond?
They have a flu outermost energy level.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many electrons are in the outermost energy level of noble gases?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Why do you think the noble gases do not have electronegativity values?
The noble gases have outer electron shells that are completely full. Therefore, they dodo not form ordinary compounds and a different method has to be used to define their electronegativity.Electronegativity for noble gases have been determined using the Allred-Rochow scales. Their values are :He=5.50, Ne=4.84, Ar=3.20, Kr=2.94, Xe=2.40.The Mulliken-Jaffe scale lists their electronegativities as:He=3.49, Ne=3.98, Ar=3.19, Kr=3.00, Xe=2.73, Rn=2.59 (F=3.91, H=2.25).The Allen electronegativity scale (Spectroscopic electronegativity scale) lists the EN of noble gases asHe=4.16, Ne=4.79, Ar=3.24, Kr=2.97, Xe=2.58 (F: 4.19, H: 2.30).The modern high level ab initio calculations indicate that neon is surprisingly less reactive than helium. The reactivity order is Ne < He < Ar < Kr < Xe < Rn
Which group on the periodic table is unreactive because its outermost energy level is full?
Noble gases are unreactive with the outermost energy level full.
How many electrons in the outermost energy level of noble gases?
8
Which group has a complete set of valence electrons in their outermost energy level?
Noble gases have a complete set of valence electrons in their outermost energy level, which is why they are known to be stable and unreactive.
Why don't noble gases normally form chemical bond?
They have a flu outermost energy level.

What contains 8 electrons in the outermost energy level?
Noble gases (except for helium which has 2 valence electrons).
How many electrons are in the outermost energy level of noble gases?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
What element has a full set of electrons in their outermost energy level?
All of the noble gases, no other elements. Helium and Neon are 2 examples of a noble gas.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
What are seven electrons in the outermost energy level?
Halogens have six valence electrons in the outermost energy level.
