- n. A soft, silvery-white alkaline-earth metal, used to deoxidize copper and in various alloys. Atomic number 56; atomic weight 137.33; melting point 725°C; boiling point 1,140°C; specific gravity 3.50; valence 2. See Table at element.
Century Dictionary and Cyclopedia
- n. Chemical symbol, Ba; atomic weight, 137.1. A chemical element belonging to the group of metals whose oxids are the alkaline earths. It is obtained as a silver-white powder, which oxidizes quickly and burns when heated in air. Its melting-point is about that of cast-iron. It does not occur native, but is found abundantly in combination in the minerals barite, barium sulphate, and witherite or barium carbonate, and less commonly in several other minerals. Barium combines with most acids to form salts which are more or less soluble in water, and these soluble salts, together with the carbonate, are active poisons.

GNU Webster's 1913
- n. (Chem.) One of the elements, belonging to the alkaline earth group; a metal having a silver-white color, and melting at a very high temperature. It is difficult to obtain the pure metal, from the facility with which it becomes oxidized in the air. Atomic weight, 137. Symbol, Ba. Its oxide called

“In their attempt to separate radium from bismuth, both contained in pitchblende, Marie and Pierre found that by crystallizing the chloride of radioactive barium from a solution, they obtained crystals that were more radioactive and richer in radium than the chloride which remained resolved.”
“The barium is thick and white and coats everything as you swallow it, and somehow this makes everything show up on the x-ray.”
“The water is also often laden with barium, which is found in underground ore deposits and can cause high blood pressure, and radium, a naturally occurring radioactive substance.”

“UNIDENTIFIED MALE: Did you indeed find lead antimony barium, which is confirmed gunshot residue, on that robe?”
“All igneous rocks contain at least a trace of barium, which is probably present in the silicates, and these small quantities are the ultimate source of the more concentrated deposits.”
“Barium swallow: It is a test which involves drinking a thick, white-colored liquid called barium before undergoing a series of X-rays.”
“The metals that produce alkalies are potassium and sodium;. the alkaline earths are formed from metals, which have been called barium, strontium, calcium, and magnesium.”

“Diagnosis may require some or all of these tests: chest X-ray cardiac MRI – a three-dimensional image shows the heart and vessel abnormalities chest CT (CAT scan) echocardiogram – sound waves create an image of the heart bronchoscopy – a doctor looks at the trachea using an instrument called a bronchoscope (while patient is under anesthesia) gastrointestinal tests such as barium swallow”
“Palin is a kind of barium meal for the US body politic: as she is ingested deeper into the system, the nastiness and sheer malevolence of the Democratic party and its bullying cheerleaders in the media are being sickeningly illuminated all around her.”
