Q. Which substance is diamagnetic?
Solution:
- Bismuth is a chemical element with the symbol Bi and atomic number 83.
- It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony.
- Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores.
- The free element is 86% as dense as lead. It is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge.
- Bismuth is the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals.
