Used for making Glass Rubber Rat poison USES

Paint Bricks Tiles Mining and refining processes CONTINUED

Not found free on earth Most common in minerals barite or witherite FOUND

Used as a weighting agent in oil well drilling Florescent lights- give fireworks their green color Help diagnose diseases or other problems in large intestine and esophagus Used in CT scans IMPORTANCE

Soft metal Silvery- white color Medium specific weight Melting point: 1,000 K or 1,340 degrees Fahrenheit Boiling point: 2,170 K or 3,450 degrees Fahrenheit Room temperature- solid state PHYSICAL PROPERTIES

Very reactive with water Barium made when chemicals combined with sulfur, carbon, or oxygen Oxidizes in air Reacts with most non-metals forming poisonous compounds CHEMICAL PROPERTIES

Alkaline Earth Metals family From Greek word barys meaning heavy Ignites when exposed to wet air Glows with exposure to light INTERESTING FACTS
