Are different atoms of the same element identical?

It's always irked me when people say in wonder that no two snowflakes look the same. I believe that no two ANYTHING look the same. But that led me to wonder if this holds true at an atomic level.

Two real atoms, i.e. that are not infinitely far from all other atoms etc., are certainly not identical. The electron density and nuclear spin densities will be affected by their environment and can even be distinguished. This is what the entire fields of MRI and NMR are based upon.
