> Given that we discover new elements[1] from time to time, it's not impossible that we'd discover a new alloy. It should still be relatively simple to identify each of the elements in it by it's atomic number. Our periodic table is complete to the 7:th row, and any unknown (un-named) element with a higher atomic number would be very likely to have a very short half life. https://en.wikipedia.org/wiki/Periodic_table https://en.wikipedia.org/wiki/Periodic_table
