2 for Helium, 8 for all others; Neon, Argon, Krypton, Xenon, and Radon
nobel gases has few electron in the outer energy level
noble gases
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
Yes, all noble gases except helium have 18 electrons in their outer energy level, which corresponds to a full valence shell. Helium has only 2 electrons in its outer shell, which is the maximum for its first energy level. The other noble gases, such as neon, argon, krypton, xenon, and radon, have 8 electrons in their outer shell, making them chemically inert and stable. The electron configuration of these elements contributes to their lack of reactivity.
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
Group 18, the noble gases, have a complete set of valence electrons in their outer energy level. This makes them stable and less likely to form chemical bonds with other elements.
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.
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.
8, with the exception of helium which has 2.
The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.
Noble gases are special because they have a complete outer electron shell, making them highly stable and unreactive. This stability prevents them from easily forming compounds with other elements. Additionally, their lack of reactivity makes noble gases useful in applications such as lighting, lasers, and as inert atmospheres.
When an electron has 8 electrons in its outer shell, it is considered to have a stable configuration known as an octet. This stable configuration is achieved by filling the outermost energy level with 8 electrons, following the octet rule.
