Isotope lists, 25-48

For an overview of available graphical representations, see Table of nuclides.

The tables listed below provide information on the basic properties of all nuclides.

• Neutron + Element 1 (Hydrogen) - Element 24 (Chromium)
• Element 25 (Manganese) - Element 48 (Cadmium)
• Element 49 (Indium) - Element 72 (Hafnium)
• Element 73 (Tantalum) - Element 96 (Curium)
• Element 97 (Berkelium) and greater

This is a pictorial periodic chart to assist in choosing the desired table from the selections above. Clicking on this chart takes you to a larger image; it does not link to the table selections.
