Conductor confusion

I posted a problem in which I asked:

Which metal is the least conductor of electricity?

I wrote Lead as the answer, but @Aryan Sanghi reported it and told that sulphur is. So, I deleted the problem.

Now, after searching a lot on Google, I found many answers. So websites say one metal, others say other, and I am really confused. These are the answers I got:

  • Lead
  • Sulphur
  • Bismuth
  • Tungsten
  • and many others.

I wish to know the correct answer to this. Any help will be appreciated.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

@Aryan Sanghi, @Steven Chase, @Arjen Vreugdenhil, please tell me what is right. Also, please forgive me if my problem was wrong. I have deleted it.

Firstly Sulphur is not a metal actually. Actually, conductivity depends on temperature. Mercury has least conductivity and maximum resistivity among metals. But, consider f-block elements and you get even more. So, your question should be Which among the following is most conductive. Hope it helps. :)

But I want the least conductive one.

Sorry, a typo. It's least conductive.

@Vinayak Srivastava Conductivity1ρConductivity \propto \frac{1}{\rho} where ρ\rho is the specific resistivity of the material. Hope it helps.

@Vinayak Srivastava,it seems that my logic also fails:-P.

mercury or pure mercury

@Aryan Sanghi, @Zakir Husain, @Kriti Kamal, @Nathan Soliman, @Páll Márton, I don't want links as I haven't studied it that much to understand the maths. I wish for a one word answer. Still, thanks for responding!

Ok, actually the answer is we don't know which metal is least conductive as there are many metals not yet discovered and every new element discovered widens the list. So, .... Hope it helps.

Ya,may but,i think.he asking from.discovered metals.

I think pure mercury.

You can't understand it properly until you don't jump into it's math.

With google translator:

  • Silver
  • Copper
  • Gold
  • Aluminum
  • Zinc
  • Nickel
  • Brass
  • Bronze
  • Iron
  • Platinum
  • Carbon steel
  • Lead
  • Stainless steel

But it still depends on many factors. Some materials will be superconducting under certain conditions and their electrical resistance will be almost zero.

@Páll Márton (no activity) That is exactly my point.

Aryan Sanghi - 3 months ago

@Páll Márton (no activity) You must study specific resistivity and math involved in it to understand the whole perfectly

@Zakir Husain Thank you! I had already read this but did not understand all its parts. My physics teacher studied about semiconductors and superconductors, so he always talks about them.

@Vinayak Srivastava - Plutonium is the answer, click this link :)

It has 2 valence electrons, that's all i know, you asked for a one word answer @Vinayak Srivastava, @Páll Márton

Why does valence electrons matter? Many elements have 2 valence electrons

It has an electrical conductivity of 0.00666 106/cm Ω, now don't ask me why, coz I'm just as confused as you guys are, silicon could also be the answer as it has electrical conductivity of 2.52E-12 106/cm Ω

@Percy Jackson It is because outer electrons of plutonium are not well shielded because of f-orbital\text{f-orbital} poor shielding and so it is unable to lose electron easily. So, it has low conductivity. Hope you understand. @Vinayak Srivastava @Percy Jackson. :)
