Why are carbon, platinum and gold inert?
Duplet or Octet configuration
The Attempt at a Solution
We use inert elements such as carbon, platinum and gold as the electrodes to prevent the electrodes react with the electrolyte. As far as I know the inert elements are noble gases only that satisfy the duplet (He element) or octet configuration.
Since carbon, platinum and gold do not satisfy the duplet or octet configuration, why are they inert?
