Is it true that the ideal gas law is only valid for hydrogen?

No. The claim that the ideal gas law is only valid for hydrogen is completely false; thermodynamic gas laws and real gas models apply broadly to many different gases, including oxygen, nitrogen, methane, and carbon dioxide.

The analysis

The claim asserts a physical impossibility that contradicts basic thermodynamics and multiple provided papers showing that the ideal gas law and equations of state apply to many gases (such as methane, oxygen, nitrogen, and carbon dioxide). Therefore, the claim is clearly refuted.
