Question

The most abundant noble gas in the atmosphere is ____.

Answer 1

Noble gas:

• Noble gases belong to Group-$18$.
• The stability of noble gases is very high.
• Noble gases exhibit stable electronic configuration due to the completely filled orbitals.
• They are fairly non-reactive gases.
• The general electronic configuration of Noble gas is ${\mathrm{ns}}^2{\mathrm{np}}^6$.

Elements of Noble gases:

• There are seven elements that make up Group-18. The elements are discussed below:

1. Helium $\left(\mathrm{He}\right)$
2. Neon $\left(\mathrm{Ne}\right)$
3. Argon $\left(\mathrm{Ar}\right)$
4. Krypton $\left(\mathrm{Kr}\right)$
5. Xenon $\left(\mathrm{Xe}\right)$
6. Radon $\left(\mathrm{Rn}\right)$
7. Oganesson $\left(\mathrm{Og}\right)$

The most abundant noble gas in the atmosphere is Argon. Argon makes up $0.94\%$ of the Earth's atmosphere.
