Which noble gas does not have eight electrons in it's highest occupied energy level?
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 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.
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.
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.
How many electrons in the outermost energy level of noble gases?
8

What contains 8 electrons in the outermost energy level?
Noble gases (except for helium which has 2 valence electrons).
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.
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 a chloride ion (Cl and ndash) in table salt?
A chloride ion (Cl⁻) has gained one electron compared to a neutral chlorine atom, which originally has seven valence electrons in its outermost energy level. Therefore, as a chloride ion, it has eight electrons in its outermost energy level. This configuration is stable and corresponds to the noble gas configuration of argon.
Do noble gases have a full octet of electrons?
If by octect you mean the outermost shell, then yes.. that's why they're noble gasses (inert)
An atom that contains 8 electrons in its outermost energy level is said to be?
Those with a stable octet are referred to as noble gases. They are highly stable elements. For eg:- Helium, Neon and Argon. A few compounds of Xenon and Argon have been formed, but these are referred as Noble gases.
