The inert gas which lies in third period is
Open in App
Solution
The correct option is C Argon
- Inert gases- The group 18 elements that have completely filled valence shells are known as inert gases as they are non-reactive in nature.
- Inert gases include Helium (period 1), Neon (period 2), Argon (period 3), Krypton (period 4), Xenon (period 5), and Radon (period 6).
- Hence, Argon lies in the third period.
