Question

Bismuth is a metal that does not conduct electricity.
A) True
B) False

Answer 1

Hint:Bismuth may be a crystalline bearing metal with atomic number 83. It’s usually mixed with metals, like lead, tin, iron. Bismuth is the diamagnetic of all metals and therefore the thermal conductivity is lower than any metal except mercury. It’s a high electric resistance .

Complete step by step answer:We define metals and non-metals based on supported properties they possess like metals are lustrous while non-metals are dull, metals are malleable and ductile whereas non-metals aren’t and metals are a good conductor of electricity but non-metals aren’t a good conductor of electricity.
Examples of metals are gold, silver, aluminum, sodium, etc. However, there are some exceptions to those properties of metals and non-metals. For instance, iodine may be non-metal but it’s not dull, it has a shiny, lustrous appearance, aluminium is metal but a poor conductor of electricity.

In the question we’ve that bismuth may be a metal that doesn’t conduct electricity. Bismuth and tungsten are two metals that are poor conductors of electricity. It conducts electricity but due to high electrical resistance bismuth a poor conductor but not an insulator(non-conductor)
So the answer to the present question is option B i.e. False.

Additional information:
 Graphite and diamond both are allotropes of carbon however diamond doesn’t conduct electricity as graphite. This is often because in diamond all the electrons within the valence shell of carbon are engaged to make a covalent bond with four other carbon atoms. Thus there’s no free electron in diamond-like graphite. However, graphite is that the only non-metal which will conduct electricity


Note:The poorest conductor of warmth among metals is Bismuth. Chrome steel is another one that’s a poor conductor of heat. Scientists have discovered that at a fraction of a degree above temperature (-273.15 degree Celsius), bismuth becomes a superconductor that’s material can conduct electricity without resistance.
