Hi Austin:

No, tin doesn't oxidize.  That's why it's used to make pewter--and line "tin" cans.  But it's very soft (malleable), which may be why it won't be used for electrical connectors.  Also, it may not be very conductive, like gold and silver.

  I thought tin oxidized over time, and gold didn't...therefore, for
  longevity, gold (or now paladium is it?) were preferred?  That is my
  understanding as to why edge connectors use gold plated fingers, isn't it?
