Does Helium Have Chemical Properties?



Helium DOES have chemical properties.

By definition, a chemical property is “any characteristic that gives a sample of matter the ability/inability to undergo a change that alters its composition.” Considering this definition, helium is matter and therefore possesses chemical properties. The fact that helium is inert and does not form compounds or react to any existing element is its chemical property….”its inability to undergo a change that alters its composition”.[“Physical and Chemical Properties of Matter” University of California Davis]

Helium Facts

Helium is a noble gas. This means it is part of a group of six gases – the others are neon, argon, krypton, xenon and radon – that have certain shared characteristics: they are colorless, odorless, are monatomic (that is, their atoms are not bound to each other) and have extremely low chemically reactive properties.

Helium has the most extreme boiling and melting point of any element.

Helium is the second most abundant element in the universe, after hydrogen.

Helium is lighter than the earth’s atmosphere, giving it the ability to cause objects to float.

Sounds also travel more quickly through helium, due to its high molar mass, which is why when inhaled your voice is altered.
