If Silver is the most conductive element, why don't we use it in electronics as opposed to Copper and Gold?

What are the disadvantages of Silver and why does Gold make a better conductor, despite the price?
gpt
Silver is the best conductor, but is expensive and oxidises easily, making it unsuitable for uses where it's exposed to oxygen or large amounts are required.  
  
Gold doesn't oxidise*, but is expensive, which is why it's often used as a coating for electronic connections like HDMI cables.  
  
Copper is abundant and has good conductivity and oxidation resistance for its price, making it the most cost effective for general use, especially when it's not exposed to air (for example in rubber coated wires).  
  
*it does, but negligibly under standard conditions.
