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.

@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 Conductivity∝ρ1 where ρ 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.

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

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

specific resistivity and math involved in it to understand the whole perfectly

@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

I have lots of electrons, but when I'm walking we can't call it ............. . What is ............. ? I don't understand you, and you don't understand me

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

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. :)
It is because outer electrons of plutonium are not well shielded because ofLog in to reply
@Aryan Sanghi!
Thank you
