Which element corresponds to the symbol 'He'?

The symbol 'He' represents the element Helium, which is a colorless, odorless, and inert gas that belongs to the noble gases group in the periodic table. Helium is the second lightest and second most abundant element in the observable universe, primarily formed through nuclear fusion in stars. Its unique properties, such as low boiling and melting points and non-reactivity, make it useful in various applications, including as a cooling medium in cryogenics and in balloons due to its lighter-than-air characteristics. Understanding elemental symbols is critical in chemistry for identifying and distinguishing between different elements, where each symbol is universally recognized and used in scientific communication.
