Table of Isotopes 3

The isotope table below shows isotopes of the chemical elements, including all presently known. They are arranged with increasing atomic numbers (proton numbers) from upper left to lower right and increasing neutron numbers from lower left to upper right for each proton number. Thus, the x axis is n-z (neutron count minus proton count), and the y axis is n-2z (neutron count minus twice the proton count). This is a bijection to the standard form, but occupies 75% less graphic area (for the known isotopes). Known isotopes occur from x of -8 to +61, and y from -69 to +4; as compared to n of 0 to 177, and z of 0 to 118.

Cell color denotes the half-life of each isotope. If a border is present, its color indicates the half-life of the most stable nuclear isomer. If you’ve scrolled so the color legend is not in view, allowing your cursor to dwell over a cell will cause a pop-up text box to indicate that isotope’s half-life. If a cell has a border, dwelling over it will also disclose the half-life of the most stable nuclear isomer state. If the isomer is more stable than the base state, the cell is further outlined in black. Cells at Dirac’s limit to Z (137) are outlined in yellow. A rough calculation of ideal z has been made, those isotopes within .2 of ideal z for a baryon count are outlined in blue. An orange outline is given for isotopes 2.5 (+/- .2) away from the ideal z (forming a pair of lines of isotopes on each side of the blue ideal line). A green outline is given for Tin and Fermium (z of 50 and 100).

Cells representing complete structures have a red !. A dashed outline is used when the structure is best for the local ridgeline. The position of the structures assume all surface monoquarks are ups – solutions with even numbers of surface downs are generally likelier. The ! boxes also include a link to a page detailing the structure (click on red ! ), often with pictures. The first structure on a ridgeline that is best fit for a ridge is outlined in turquoise. The table is extended leftward through anti-oxygen, but showing all anti-matter isotopes seems redundant. The outer edge of the table includes links to element information, both the element page from Wikipedia, and the isotope list for the element. Full lists of solutions are in the complete structure table (linked above). Almost all complete structures have trimmed and extended variants galore.

Note – this table was built from the Wikipedia table of isotopes, expanded by isotope data from multiple sources, so may have some inaccuracies. Structure links were built manually, and are even likelier to show human error. Please report errors to the author. Fair use is assumed, no copyright infringement is intended.
