Utdragsvätska Till Isotopgenerator 250 ml - Alega Skolmateriel

Because of its high chemical reactivity, barium is never found in nature as a free element. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Barium – Properties Barium (barium sulphate) powder mixed with water can be swallowed (flavouring may be added) or introduced to the bowel as an enema through a tube inserted into the rectum. The mixture passes quickly into your digestive tract, and its progress is followed by taking x-rays over different periods of time, depending on which part of your digestive tract the doctor wants to observe. Barium ek chemical element hae, jiske symbol Ba, atomic number 56 aur mass nuber 137.3 hae.
