Puddenphatt & Monagham Periodic Table
Jeries Rihani's version of R. J. Puddenphatt and P. K. Monaghan, published in1989, but is not an exact copy. The differences are as follows:
- It adds color: YELLOW for the s-block, GREEN for the p-block, BLUE for the d-block and PURPLE for the f-block.
- It avoids being congested since it excludes the electronic configurations of the elements.
- It is updated and includes the atomic numbers 119 and 120.
- It shows that it is symmetrical around the vertical axis.
- The f-block, like all the other blocks, ends with even atomic numbers.
Puddephatt and Monaghan say "their table is after Philips and Williams":
