Yes. it is filled.
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.
The noble gases family in Group 18 have a filled outer energy level, making them very stable and unreactive.
Group 18 aka the Noble Gases / Inert Gases.
A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.
All of the Noble Gases, which are on the right side of the periodic table, have a full outer energy level. The elements that are Noble Gases are the following: Neon Argon Krypton Xenon Radon Ununoctium
yes.they have the maximum number of electrons in their outer energy level?
Their outer energy levels are completely filled.
Helium is considered unreactive because it has a filled outer energy level with two electrons in its 1s orbital. This makes it very stable and unlikely to form chemical bonds with other elements.
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.
8, with the exception of helium which has 2.
Their outer energy levels are completely filled.
filled. That would be 2 electrons for helium, and 8 electrons for the rest of the noble gases in group 18 on the periodic table.
