Question

give reason for the fact that noble gases are least reactive.

Answer 1

⇒ Noble gases are those gases which are totally unreactive.
⇒They are odorless, colorless and are monatomic gases
⇒Mainly , there are six noble gases :
*Helium
*Neon
*Argon
*Krypton
*Xenon
*Radon
⇒The reason for their low reactivity is that there valence electrons are full.
⇒There is no need for them to gain or lose electrons.
⇒Therefore they need not react with any other elements.
⇒Due to the property of noble gases of non reactivity , they are also known as inert gases.
