Material properties challenge

  1. Feb 23, 2009 #1
    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:

    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.
