Can't you take a proton out of a mercury atom for example so the atomic number can change from 80 to 79 so it can become a gold atom?

Very funny but can't you use nuclear binding energy...
 
So are you saying it's impossible...
 
It called transmutation. It's 60+ years old now in the lab, maybe 80 years old on paper.

Exactly. This is after all the technique used to create elements that have never been seen before.

There's one catch: It's expensive. Massively expensive. The cost of creating gold via transmutation exceeds the value of the gold by many, many orders of magnitude.
 
Oh ok that's pretty interesting..
