While we know about these major components, there's still a lot we don't know about Uranus's atmosphere. However, based on our current understanding, here are some gases that are unlikely to be found in significant quantities:
* Oxygen (O2): Oxygen is very reactive and would likely be quickly consumed in chemical reactions.
* Nitrogen (N2): Nitrogen is found in Earth's atmosphere, but it's not a major constituent of Uranus's atmosphere.
* Carbon dioxide (CO2): While CO2 is present in small amounts, it's not a significant component of Uranus's atmosphere.
It's important to remember that our understanding of Uranus's atmosphere is constantly evolving, and new discoveries might change our knowledge.
