Barium is a soft silvery -white metallic alkaline earth metal, with the chemical symbol Ba, and atomic number 56. The element derives its name from the Greek word "barys," meaning heavy, indicative of its high density. It is also harder than most alkaline earth metals. At room temperature, it remains in a solid state. Barium is highly reactive with air, forming a protective oxide layer on its surface, preventing further oxidation. It readily reacts with water to produce hydrogen gas and barium hydroxide. It also forms compounds with various other elements, including sulfur, carbon, and halogens - these compounds are toxic and must be hanfled with caution.
