Discussion Overview

The discussion revolves around the nature of superconductivity in chemical elements, specifically questioning whether all elements can exhibit superconductivity and the relationship between diamagnetic materials and superconductivity.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • Some participants question whether all chemical elements can be superconductive, with a distinction made between elemental solids and free atomic elements.
  • One participant asserts that elemental solids can be superconductors, citing mercury as an example, but emphasizes that not all elements are superconductors.
  • There is uncertainty regarding the conditions (such as temperature and pressure) under which certain elements, like copper and gold, may become superconductors.
  • Another participant clarifies that the existence of diamagnetic materials with no unpaired electrons does not imply that only such materials can be superconductive.

Areas of Agreement / Disagreement

Participants express differing views on the conditions required for superconductivity and the nature of elements that can be superconductors. There is no consensus on whether all elements can be superconductive.

Contextual Notes

Participants highlight the need for careful reading of statements regarding superconductivity and the conditions under which elements may exhibit this property, indicating potential limitations in understanding the broader implications.

Hi

1) Can all chemical elements be superconductive?

2) It is said that in diamagnetic materials there are no unpaired electrons. Does this mean that only such materials can be superconductive?

This is vague. Are you asking of a metal made of just one element can be a superconductor? Then yes. Hg, the first superconductor discovered, is made up of just one element. If you are asking if a free atomic element can become a superconductor, then that question makes no sense because an element isn't a solid and has no "conduction" properties.

Not all elements are superconductors, i think so, or at least we don't know conditions (temperature, pressure) should be for some elements such as copper , gold to become superconductors

You need to read the statements carefully. I said that elemental solids CAN be a superconductor. That statement does NOT imply that ALL elements are superconductors!
