The chemical entities present in thermosphere of the atmosphere are
Options
- AO ₂⁺, O ⁺, NO ⁺
- BO ₃
- CN ₂, O ₂, CO ₂, H ₂ O
- DO ₃, O ₂⁺, O ₂
Correct answer
A. O ₂⁺, O ⁺, NO ⁺
Step-by-step solution
The thermosphere is the fourth layer of the earth's atmosphere and is located above the mesosphere. The air is thin in the thermosphere. The earth's thermosphere also includes the region of the atmosphere, called the ionosphere. The ionosphere is the region of the atmosphere that is filled with charged particles such as O ₂⁺ , O ⁺, NO ⁺ . The high temperature in the thermosphere can cause molecules to ionize.
