Difference Between Helium and Oxygen | Helium vs Oxygen

Oxygen: Compared to Helium, the chemical reactivity of Oxygen is extremely high. Even though it is a dimolecular stable gas at room temperature, it quickly reacts with so many elements and compounds. However, Oxygen does not react with itself, Nitrogen, acids, bases and water under normal conditions. Oxygen can act as both oxidizing agent and ...

Inert gas asphyxiation Wikipedia

Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, rather than atmospheric air (which is largely composed of nitrogen and oxygen). Examples of physiologically inert gases, which have caused accidental or deliberate death by this mechanism, are argon, helium, nitrogen and methane.
