Depending on what its electrons are doing and what it's bonded to, it might be part of a chemical that is silver coloured or black or blue or shiny or poisonous or a cure for disease, but whatever it is, that atom is still silver and will remain an atom of silver probably forever because that core number is very, very difficult to change. Now you might notice something weird about silver here: its chemical symbol, the one or two letter short code that tells you what it is, is Ag. Not Si, which is silicon, or Sv which is perfectly available, but Ag.
