AI overview
Helium is a lightweight, colorless gas that is chemically inert (meaning it doesn't react with other elements) and the second-most abundant element in the universe after hydrogen. It matters because of its unique properties—it has the lowest boiling point of any element and remains useful in various scientific and industrial applications due to its inert nature.
