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

In summary, the conversation discusses different materials and their properties in terms of electron affinity and conductivity. The materials mentioned include one with a high electron affinity and good conductivity, one with a mid-range electron affinity and poor conductivity, and one with a low electron affinity and good conductivity. The speaker also mentions the importance of specifying the range of values when discussing these properties.

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.
