Basically all the noble gases as they have a stable electronic configuration and therefore they would not share their electrons with other atoms.

Actually, the noble gases have been synthesized in labs to form noble gas compounds. Gold and platinum are both unreactive elements. There are probably more though.
The element with the electron configuration 2 8 is oxygen, which has 8 electrons in total.
Most elements are completely stable and safe. However, the safest elements would be the most unreactive. So, in that sense, the Inert Gases (exc. Radon, which is radioactive) are probably the safest group of elements, as they are completely unreactive.
The element you are referring to is neon. Neon is a noble gas known for being colorless, odorless, and extremely unreactive. It is commonly used in electric lights and neon signs due to its ability to produce a bright red-orange glow when electrified.
Sodium is not an unreactive element. It is a highly reactive metal that readily forms compounds with other elements, especially in the presence of water to form sodium hydroxide and hydrogen gas. Sodium is stored under oil to protect it from reacting with air or moisture.
Copper can sometimes be found native because it is relatively unreactive and does not easily form compounds with other elements. This allows it to exist in its pure metallic form in certain geological environments where it has been concentrated and deposited by natural processes.
helium
Argon is the most unreactive in this series. Cheese is not an element; it is a mixture of compounds.
Krypton is an unreactive gas.
Balls
Inert.
Neon (Ne) is a noble gas, very unreactive.
Because helium is an unreactive chemical element.
Noble gases are not magnetic because they have a full outer electron shell, making them stable and unreactive with magnetic fields.
Neon!
Noble gases are very unreactive.
Argon.
The element is 'argon' and belongs to noble gas family.
