Does Helium support combustion?

Helium does not support combustion because it is an inert gas, meaning it does not react chemically with other substances, including those that are combustible. Inert gases like helium have a full valence shell of electrons, which makes them stable and unlikely to engage in chemical reactions that would lead to fire or combustion. This characteristic is especially important in various applications, including medical, industrial, and scientific settings, where preventing combustion is critical for safety.

In contrast, any assertions regarding specific mixtures or larger quantities influencing helium’s ability to support combustion are unfounded, as helium retains its inert properties regardless of the conditions it is in. Thus, the assertion that helium does not support combustion is accurate and aligns with its well-documented chemical behavior.
