Question

Name the most abundant noble gas present in the air.

Answer 1

• Noble gases are also known as inert gas because they are unreactive as they have completely filed valence shell electronic configuration $\left({{\mathrm{ns}}^2}^{}{\mathrm{np}}^6\right)$ , hence they do not have any tendency to make bonds.
• The earth's atmosphere contains about 78 % nitrogen, 21 % oxygen, 0.9 % argon, and 0.1 % other gases.
• Argon is the most abundant noble gas present in the air because it is a highly unreactive and relatively heavy gas.
