Helium
Helium is considered the most unreactive gas because it is a noble gas with a full outer electron shell, making it very stable and unlikely to react with other elements.
An unreactive gas is called inert gas. These gases are also known as noble gases because they are very stable and do not easily undergo chemical reactions with other elements. Examples of inert gases include helium, neon, argon, krypton, xenon, and radon.
The unreactive gas in the second period is neon (Ne). It belongs to the noble gas group on the periodic table and is known for being chemically inert and not readily forming compounds with other elements.
Argon is a noble gas and is generally unreactive. It does not react with water or most other substances under normal conditions due to its stable electronic configuration.
The most unreactive elements are found in the noble gas group (Group 18) of the periodic table. These elements have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements.

Helium (or alpha particles)
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).
Nitrogen.
No. Neon is a noble gas and is unreactive.
The element is 'argon' and belongs to noble gas family.
An unreactive gas is called inert gas. These gases are also known as noble gases because they are very stable and do not easily undergo chemical reactions with other elements. Examples of inert gases include helium, neon, argon, krypton, xenon, and radon.
Krypton is an unreactive gas.
No. Neon is a noble gas and is unreactive.
Nitrogen gas (N2) is generally unreactive due to its triple bond between the two nitrogen atoms, which requires significant energy to break. This makes nitrogen gas stable and unreactive under normal conditions.
The unreactive gas in the second period is neon (Ne). It belongs to the noble gas group on the periodic table and is known for being chemically inert and not readily forming compounds with other elements.
