N2, nitrogen is about 78% in air but does not take part in several reactions as oxygen does so we can say that after noble gases Nitrogen is the least reactive gas or element.
Noble gases are very unreactive.
Unreactive
Noble Gasses.
No, magnesium is not a property of noble gases. Magnesium is a chemical element classified as an alkaline earth metal, while noble gases are a group of elements known for their stable and unreactive nature.
In short, an element's valence shell is full and most stable when it contains eight electrons (this stability is the reason that the noble gases are so unreactive).
Noble gases are not magnetic because they have a full outer electron shell, making them stable and unreactive with magnetic fields.
The full octet means the element is inert (non-reactive.)
Helium, Neon, Xenon, Krypton, Radon, and Argon.
Correct.
most noble gases exist in their pure form because they are so unreactive
Nobel gases are very unreactive.
A colorless, odorless, highly unreactive gaseous element. Xenon and similar elements are called Noble Gases
