According to the Group Displacement Law (Rutherford-Soddy rules), what is the net periodic table shi — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

One $\alpha$ -emission reduces the atomic number ($Z$) by 2. Two subsequent $\beta^-$ -emissions increase $Z$ by a total of 2. The net change in $Z$ is zero, meaning the final product is an isotope of the parent element and occupies the identical group.
