The concept of isotope was a very significant advance in the understanding of radioactivity. But two fundamental questions were still on the table, namely, how

The new 'elements' of the radioactive series
The discovery that there were several radioactive series each containing apparently new substances, created a serious problem. In 1910, there were still some empty spaces
The impurity, by definition, of radioactive samples
It is perhaps appropriate at this point in our exploration of the atomic nucleus to stop for a moment to consider what it means from
Radioactive transformation
Rutherford and Soddy proposed a very bold model of radioactive transformation to explain the nature of these changes. They suggested that when a radioactive atom
The radioactive decay series
Detailed studies of the decay of radium and its derivatives led to the discovery that radioactive transformation resulted in a stable end product that was
