By reacting, an element that does not have a complete set of valence electrons can acquire an electron configuration similar to that of a noble gas. why is a noble gas different from other elements?

A noble gas is different from other elements because they are the most stable elements that can have the maximum number of valence electrons on their outer shells. This characteristic allows the noble gases to rarely react with other elements, unlike all the other elements found within the periodic table. Nobel gases are found in the group 18 of the periodic table and these are Argon, Neon, Krypton, Xenon, Organesson, Helium, and Radon.
