  1. Helium is a chemical element represented by the symbol "He" and atomic number 2 on the periodic table. It is a colorless, odorless, tasteless noble gas that exists in the atmosphere in extremely small quantities. Helium is the second lightest and second most abundant element in the universe, after hydrogen.

    At standard conditions, helium is a gas that remains in a liquid state at extremely low temperatures. It possesses unique properties such as low boiling and melting points, which make it suitable for various applications. Its name is derived from the Greek word "helios," meaning sun, as it was first discovered by astronomers during observations of a solar eclipse.

    Helium is primarily obtained through natural gas extraction, as it accumulates in certain underground deposits over millions of years. It has several key uses, most notably in cryogenics, where its low temperatures are crucial for superconducting magnets and cooling scientific equipment. Additionally, helium is widely employed as a lifting gas for blimps, party balloons, and airships due to its lighter-than-air properties.

    In the medical field, helium-oxygen mixtures are utilized to treat respiratory conditions, while in industrial applications, helium is employed for leak detection, as a shielding gas in welding, and in various analytical instruments. Helium is chemically inert, meaning it does not readily react with other elements, making it a valuable gas for specific purposes. However, its limited supply has prompted concerns about conservation and responsible usage.
