There are numerous medical applications of radioactive isotopes, which we have already touched
upon in the class. Instead, let's take this opportunity that chemistry was forged in the pseudoscience
of alchemy. One of the largest goals in alchemy was the transmutation of lead into gold, which we
understand to be impossible given normal chemical reactions. However, this process can be
accomplished (at prohibitive cost) using nuclear reactions! Let's investigate it further.
Question 1
O pts
The transmutation of lead into gold is not direct. We are limited by the types of nuclear decay we've
seen in class. The difficult arises from the fact that there is only one stable (non-radioactive) isotope
of gold, 197 Au. Every other isotope is radioactive and will undergo decay in some way. Fill in the
blanks in the answer box below to see which isotopes of gold decay to which elements. If you prefer
to upload an image using the rich text editor, that's fine as well.
