Che metallo e il bismuto?
Il bismuto è l'elemento chimico di numero atomico 83 e il suo simbolo è Bi. È un metallo pesante e fragile, di aspetto bianco-roseo e il cui comportamento chimico è simile a quello dell'arsenico e dell'antimonio.
Come faccio a sapere quanti elettroni di valenza ha un elemento?
Gli elettroni di valenza sono indicati nella tavola periodica dal numero romano posto all'apice della colonna su cui è collocato l'elemento (gruppo). Per esempio, H, Li, Na, K, Rb e Cs hanno tutti quanti un solo elettrone di valenza, infatti appartengono al gruppo I.
What are the commercial applications of bismuth?
- Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials. In the United States, for example, 733 tonnes of bismuth were consumed in 2016, of which 70% went into chemicals (including pharmaceuticals, pigments, and cosmetics)...
What is the difference between bsbismuth and BSCCO?
- Bismuth is included in BSCCO (bismuth strontium calcium copper oxide) which is a group of similar superconducting compounds discovered in 1988 that exhibit the highest superconducting transition temperatures. Bismuth subnitrate is a component of glazes that produces an iridescence and is used as a pigment in paint.
What is the difference between bismuth oxide and bismuth germanate?
- Bismuth oxide, in its delta form, is a solid electrolyte for oxygen. This form normally breaks down below a high-temperature threshold, but can be electrodeposited well below this temperature in a highly alkaline solution. Bismuth germanate is a scintillator, widely used in X-ray and gamma ray detectors.
How does bismuth subsalicylate work to treat diarrhea?
- It works by decreasing the flow of fluids and electrolytes into the bowel, reduces inflammation within the intestine, and may kill the organisms that can cause diarrhea. How should this medicine be used? Bismuth subsalicylate comes as a liquid, tablet, or chewable tablet to be taken by mouth, with or without food.
