The percentage of hydrogen on earth is just 0.25%
The approximate percentage by volume of oxygen in Earth's atmosphere at location 2 is around 21%.
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.
About 50% of the sun's radiation that reaches Earth's atmosphere is absorbed by the Earth's surface. The remaining energy is either reflected back to space or absorbed by the atmosphere.

Yes. Hydrogen is part - albeit a very small part - of the Earth's atmosphere. Typically it makes up about 0.000055% of the atmosphere
Hydrogen and helium
By volume, hydrogen accounts for around 0.000055%.

The atmosphere of Titan is mostly nitrogen with a small percentage of methane and hydrogen.
