What materials have high, mid-range, and low electron affinity and conductivity?

Click For Summary

Discussion Overview

The discussion revolves around identifying materials categorized by their electron affinity and electrical conductivity. Participants seek examples of materials with high, mid-range, and low electron affinity, along with their respective conductivity classifications.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant requests examples of materials with specific properties: high electron affinity and good conductivity, mid-range electron affinity and poor conductivity, and low electron affinity and good conductivity.
  • Another participant challenges the vagueness of terms like "high," "good," "poor," "low," and "midrange," arguing that without specified ranges, interpretations may vary significantly.
  • A participant clarifies that their use of "high" and "low" is relative to other materials, but another participant questions how this relativity is defined and what benchmarks are being used for comparison.
  • One participant suggests that silicone rubber has a high electron affinity relative to aluminum and is a poor conductor, introducing a specific example into the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions of the terms used in the original request, leading to ongoing debate about the criteria for categorizing materials.

Contextual Notes

The discussion highlights a lack of clarity regarding the specific ranges and definitions of electron affinity and conductivity, which may affect the identification of suitable materials.

Can anyone name for me:

a] a material that has a HIGH electron affinity and is a GOOD conductor of electricity.

b] a material that has a MID-RANGE electron affinity and is a POOR conductor of electricity.

c] a material that has a LOW electron affinity and is a GOOD conductor of electricity.

Bonus points if you can guess what I'm going to do with these materials.

These properties are VAGUE!

What do you mean by "high", "good", "poor", "low", and "midrange"? If you do not specify range of values, your "good" could easily be my "poor".

I mean relative to each other.

Sorry for assuming you could have inferred that.

Er.. how is that clear?

For example, look at your first criteria:

a material that has a HIGH electron affinity and is a GOOD conductor of electricity.

What am I comparing here if I'm doing this "relative to each other"? If I'm opening up the CRC Handbook, what am I comparing?

I would say that relative to aluminum, silicone rubber has a high electron affinity and is a poor conductor.
