It is easy to find in the figure that valuable deviations from the line of the trend are present in the region from Bismuth to element 104, then to element 119 where the deviations from the line of the trend are high (especially--in the region of the already synthesized superheavy elements 104-118).
In addition, the panel selected the name dubnium for element 104, joliotium for 105, and rutherfordium for 106.
Figure 3 in Page 68 shows a shift of the atomic mass just element 104, before Period 8: in element 118 the atomic mass is shifted for 11 units; in Period 9 the shift exceeds 15 units, and then it increases upto 21 units.
