The element is 'argon' and belongs to noble gas family.
The unreactive elemnyt in period 3 is Argon, Ar, a noble gas
Helium, Neon, Xenon, Krypton, Radon, and Argon.
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
Argon.
Argon is more dense than air.
the basically unreactive gas argon (element) is in a light bulb to prevent the tungsten (element) filament from coming into contact with oxygen (element) and getting oxygenated.
Krypton is an unreactive gas.
Neon (Ne) is a noble gas, very unreactive.
Argon
The element is 'argon' and belongs to noble gas family.
Element 118 is a noble gas, which means it would be largely unreactive. Only a few atoms of this gas have been synthesized.
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.
Helium (or alpha particles)
The unreactive elemnyt in period 3 is Argon, Ar, a noble gas
Xenon is a colourless, odourless dense gas. It is very unreactive.
