Problem
A segment of first-ionization energy data for successive elements is listed below:
Z = 11 496 Z = 12 738 Z = 13 577 Z = 14 786 Z = 15 1012 Z = 16 999 Z = 17 1251 Z = 18 1521 Z = 19 419
Identify the atomic number at which the data indicate the start of a new principal electron shell, and justify your answer using the trend in the listed values.
