| Element Symbol Mowery Standard ISOTOPE Number PERIODIC ATOMIC MASS OF ISOTOPE Measured Atomic Mass Element Name |
| Colored entries indicate the correlation between Measured Atomic Mass and the "ALTERNATE PERIODIC PROGRESSION of an isotopes atomic mass. |
| Isotopes in the elements La and Ce deviate from the periodic progression of Isotopes. The Periodic progression suggests that a stable isotope of 137 should exist. . Yet the very unstable Isotope 139 is shown as a progression of the right side isotopes. Cerium also does not illustrate the progressive isotope 139. Without 139 and its Hydrogen content, this element would be in the form of a gas or measured in the form of a gas. |
