@CityGlobeTour ********************************* Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, and inert noble gas. Helium is the second most abundant element in the observable universe, after hydrogen, and it is the second lightest element as well. Here are some key characteristics and uses of helium gas: 1 - 0Low Density: Helium is known for its low density, which makes it lighter than air. Because of this property, helium is often used to fill balloons, blimps, and airships to make them float. 2 - Inertness: Helium is chemically inert, which means it does not readily react with other elements or compounds. This makes it safe to use in various applications, including as a coolant in certain scientific and industrial processes. 3 - Cryogenic Applications: Helium is commonly used in cryogenic applications due to its extremely low boiling point, close to absolute zero (°C or °F).
