核素图 Table of nuclides

(重定向自Isotope table)
核素图(为显示方便,划分成三个部分)
Fragment of table of nuclides for Polonium, Radium, Copernicium and Curium, as seen on a monument in front of University of Warsaw's Centre of New Technologies
Exemple de diagramme de Segrè. Sur celui-ci figure aussi le type de radioactivité du noyau : les noyaux stables possédant peu de nucléons se trouvent dans la vallée de stabilité, le long de la bissectrice du diagramme

核素图核素表是一个二维图表。其中一维表示核素的中子数,另一维表示它的质子数。因此图中的每一点代表某个元素真实存在的或者假想的核素。相比于更关注化学性质的元素周期表,这套标度系统能够提供更多的同位素信息。

A table of nuclides or chart of nuclides is a two-dimensional graph in which one axis represents the number of neutrons and the other represents the number of protons in an atomic nucleus. Each point plotted on the graph thus represents the nuclide of a real or hypothetical chemical element. This system of ordering nuclides can offer a greater insight into the characteristics of isotopes than the better-known periodic table, which shows only elements instead of each of their isotopes.
