nuklidtáblázatot

The term "nuklidtáblázatot" translates from Hungarian to English as "nuclide chart." A nuclide chart, also known as a Segrè chart or a chart of nuclides, is a graphical representation of all known nuclides. It is a fundamental tool in nuclear physics and chemistry for organizing and visualizing information about atomic nuclei.

Typically, a nuclide chart is displayed with the number of neutrons on one axis and the number of protons (atomic number) on the other. Each point on the chart represents a specific nuclide. Different colors or symbols are often used to distinguish between stable nuclides, radioactive isotopes (radionuclides), and sometimes even synthetic or exotic nuclei. The chart also frequently indicates decay modes and half-lives of radioactive isotopes, providing a comprehensive overview of nuclear properties.

The arrangement of nuclides on the chart reveals important trends and relationships. For instance, the "valley of stability" – a region of relatively stable nuclides – is clearly visible, illustrating why certain combinations of protons and neutrons lead to more stable nuclei. Nuclides lying outside this valley are generally radioactive and tend to decay towards stability. The nuclide chart is indispensable for understanding nuclear reactions, predicting decay pathways, and identifying suitable isotopes for various applications, such as medical imaging or nuclear energy.
