Barium’s Overview Barium is a soft and silvery-white, metallic element. It belongs to the alkaline earth group and chemically resembles calcium. Barium only occurs in combinations with other elements, some of the most common being sulfur, carbon, or oxygen. The metal also oxidizes quickly in air and strongly reacts with water. Though Barium is not extensively used in the world. One of its most interesting uses is that it can give fireworks a green color. Barium is a key, complex element to our life, and serves many interesting purposes in the scientific community. 3

Who Founded/Invented Barium? The word Barium comes from the Greek word for heavy, barys . Barium is never freely found in the wild so it was discovered through experimental research. In the 1600s Vincenzo Casciarolo found these unique pebbles that if they were heated to the point where they became red during the day, then they would shine at night. What he had discovered was Barium sulfate. In the 1760s Carl Scheele studied these pebbles again and realized that it was the sulfate of another element. Also during this time a mineralogist named, Dr. William Withering had discovered a heavy metal in a lead mine that was simply not lead. This mineral was Barium carbonate. Eventually, Barium was first discovered by Sir Humphry Davy in 1808. Sir Humphry Davy discovered it through the electrolysis of hydroxide.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
