Summerize why people were unsuccesful over 1,000 years ago when they tried to transform lead into gold. What process would they have needed to complete in order to have been successful?

#See solution for details.

Explanation:

-The process of converting one chemical into another is called Nuclear Transmutation.

-A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay (where no outside particle is needed).

-This process was not yet developed 1000years ago thus the inability to convert lead into gold back then.

-The process didn't exist and wasn't applied in modern physics until 1901 by Frederick Soddy together with Ernest Rutherford discovered the radioactive Thorium.
