These are the noble (inert) gases.
This is the noble gases familiy.
Noble gases have a full outer electron shell, making them stable and unreactive. Their electron configuration does not easily allow them to gain, lose, or share electrons with other elements. This lack of reactivity is what gives them their name "noble."
Noble gases, such as helium, neon, and argon, will never react with other elements. They have a full outer electron shell, making them stable and unreactive.
chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.

valence shell
Noble gases actually have the most stable electronic configurations in the periodic table due to having a full outer shell of electrons. This full octet makes them less likely to react with other elements, earning them the name "noble gases."
Elements with 2 or 8 electrons in their valence shell are generally known as inert or noble gases. These elements are very stable and unreactive due to their full outer electron shells. Examples include helium, neon, and argon.
The outer covering of an egg is called the shell.
The outer shell of an atom is the valence shell, which contains the valence electrons.
Helium, neon, and argon are called inert gases because they are chemically stable and do not easily react with other elements to form compounds. They have a full outer electron shell, making them very unreactive under normal conditions.
Helium is an element. It is a Noble Gas (group 8) which means it has a full outer shell and is not reactive. It's symbol is He.
