Why are nobles gases special?
Noble Gases have an 'octet' which is a completely filled outer energy level with 8 electrons, except for Helium which has 2 valence electrons. This makes these gases in group 18 very stable.
What element has three or fewer electrons in the outer energy level?
nobel gases has few electron in the outer energy level
What group of elements has a stable amount of electrons in their outer level?
noble gases
Which group has a complete set of valence electrons in their outer energy level?
noble gases
Which group has a stable number of electrons in their outer most energy level?
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
What a gas in the rightmost column of the periodic table with a full outer energy level?
Noble gases are the gases in the rightmost column of the Periodic Table that have a full outer energy level. This is why the noble gases do not react with other elements readily. When an atom has a full outer energy level, it means that it has the maximum number of electrons in these outer shells, making it stable.
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 are the nobles gases nonreactive?
They are already balanced. They have a full outer shell.
What is meant by neutral gases?
Chemically, a neutral gas is one that is stable (meaning it has 8 valence electrons in its outer level already and does not need to react to achieve these 8 electrons). These gases are also called Noble gases. Helium is considered a neutral gas because it only has one energy level and can only hold 2 electrons (Remember that the goal of elements is to achieve stability, which is why they react. An element is stable when it has 8 electrons in the outer level).
What is the group number for elements that have a stable number of electron spin their outer energy level?
The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.
How many electrons in sulfurs outer level?
There are 2 electrons in the inner level, 8 electrons in the middle level, and exactly 6 electrons in Sulfurs outer level.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
