WebA suspension of barium sulfate is sometimes given to patients suffering from digestive disorders. This is a ‘barium meal’ or ‘barium enema’. Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and intestines can be distinguished on an X-ray. Barium carbonate has been used in the past as a rat poison. WebOct 7, 2024 · Updated on October 07, 2024. The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more ... banir dinding

WebQuestion: d) How would you expect the behavior of cesium (Cs) in water to compare with the behavior of Rb in water? Briefly explain. (e) How would you expect the behavior of barium (Ba) in water to compare with the behavior of Cs in water? Explain. 2. A diet high in Al has been associated with the development of certain neurological disorders. There is no unique and fully consistent way to define the reactivity series, but it is common to use the three types of reaction listed below, many of which can be performed in a high-school laboratory (at least as demonstrations). The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: WebMar 30, 2024 · Caesium is more reactive. Generally as you go down the periodic table, electro-positivity increases. However, for the really heavy elements, the presence of so many positively charged protons in the nucleus has the affect of causing the electrons to move round at incredibly fast speeds approaching the speed of light. asam lambung naik ke dada
