Barium is the 56th element in the modern periodic table.
is located in group 2 in the periodic table. Barium is one of the alkaline earth metals. Its .
name comes from the Greek word barys witch means heavy or dense. Barium is a silver-.
white, highly reactive, metallic element. It has an atomic mass of 137.33 amu. The .
element's melting point is 850 ∘C and the boiling point is 1537 ∘C. It has a specific .
gravity of 3.5 at 20 ∘C . Barium has a density of 3.51 g/cm. The element's hardness is.
comparable to that of the lead. It is the only alkaline earth metal that has a body-centered .
cubic crystal structure. It has a valence 2+ and has 6 energy levels. Barium is the 14th.
most common element and makes up 1/2000th of the crust of Earth. Barium was.
discovered in 1808 in England by Sir Humphrey Davy.
Barium is never found in nature in an element form. It reacts with almost all the.
nonmetals. It is mostly found in the minerals witherite, a barium carbonate( BaCO1) and.
barite, a barium sulfate (BaSO4). It is also found in most soils at a low level. Barium.
burns easily in the air and reacts with water to produce hydrogen. Barium reduces water.
and dilutes acids to hydrogen. When it burns in the air, it produces peroxide, which .
produce hydrogen peroxide when treated with water. At room temperature, Barium forms .
oxides. All of the water-soluble and acid-soluble barium compounds are poisonous. The.
element may spontaneously ignite in moist air. Because it's extremely reactive, Barium is .
never found in pure form and must be stored under kerosene to remain pure. .
Barium has uses mostly in medical and industrial applications. In the medical .
application, Barium enema is used to detect colon cancer. Radiologists use barium sulfate .
to examine a patient's intestines with a X-rays. When a patient drinks a suspension of.
barium sulfate in water or barium enema, the barium sulfate particles temporarily fill the.
The alkaline earth metals contain beryllium, magnesium, calcium, strontium, barium, and radium. ... Label the micropipets calcium, strontium, barium, and sodium. 3. ... Repeat steps 4 through 11 with the barium and oxalate solutions. 14. ... For the Barium Nitrate, the well with the most precipitate was H-5. ... The ratio of the Barium was 5:5. ...
However, a colonoscopy is more expensive than a barium enema. ... A mixture of barium and water is passed into the patient's colon through the tube. ... After the technologist is finished, the barium will be released back into the bag and the patient is allowed to go to the bathroom to try and release the rest of the barium. ... The patient should drink lots of fluids to help get rid of the barium. A mild laxative may also be taken to help clear the barium. ...
The second part of this lab dealt with analyzing how much sulfate was in the barium sulfate and then calculation of errors. ... Some of these could have been that the barium sulfate did not digest long enough so big enough crystals were not produced and the barium sulfate passed through the filter paper with the water. ... Also if the barium sulfate started to boil some of the solution could have boiled out of the beaker, and finally if there was not enough barium chloride used to precipitate out all of the barium sulfate then the sulfate would have remained an ion in the solution and passed...

To their dismay, Hahn and Strassman produced barium in their experiment which was unjustly ruled as an impurity. ... Meitner concluded that a Uranium nucleus had split during this reaction producing a source of tremendous amount of energy along with the Barium and other elements. ...
Objective: In this experiment you will investigate the differences between physical changes in matter. You will be expected to perform several short exercises and observe the changes that occur during each. You will then determine if your procedure resulted in a chemical or physical change. Sa...
