Inert gas element which has a different valence shell configuration
Answers
Answer:
Helium
Explanation:
Helium has 2 electrons in its outermost valence shell while the other inert gas has 8 electrons in its outermost valence shell.
Answer:
Concept:
Helium is a stable isotope He and the atomic number 2 (from Greek: o, romanized: helios, lit.'sun'). It is the first noble gas in the periodic table and is colourless, odourless, tasteless, non-toxic, inert, monatomic gas. [a]Its melting and boiling points are the lowest of all the elements. It is the second lightest and second most abundant element in the visible universe (hydrogen is the lightest and most abundant). It makes up nearly a quarter of the total element mass, which is more than a dozen times the size of all the heavier elements put together. Bang. Nuclear fusion of hydrogen produces a large amount of new helium in stars.

Answer:
The answer is Helium
The outermost valence shell of helium has two electrons, while the outermost valence shell of the other inert gas has eight. Inert gases are inactive elements that do not participate in chemical reactions. They are stable because their Valence shell is entirely filled, and they do not need to gain or lose atoms to be stable. As a result, their valency is zero.As is well known, inert gases have 0 valencies since their outermost shell contains 8 electrons (expect for Helium, which has 2 valence electrons). Be a result, they are referred to as "inert" because they have no propensity to interact with other components.
