Interactive periodic and isotope table

This page shows an interactive periodic and isotope table. Use the mouse to navigate the isotope table and display detailed element/radioactive decay information. Click to lock to a specific element, click again to lock to the isotope to make navigation easier. All of the data is parsed from Wikipedia; accuracy not guaranteed.

Decay types:

• α Alpha decay, the emission of a helium nucleus. Reduces the atomic number by two and mass number by four.
• β^- Beta decay, in which an electron and neutrino are emitted. Leads to the conversion of a neutron into a proton.
• β⁺ Positron emission, like beta decay, but with the emission of a positron (anti-electron). A neutron is converted into a proton.
• ε Electron capture. An inner-shell electron is captured by a proton in the nucleus, forming a neutron and neutrino.
• p Proton emission. A proton is emitted from the nucleus with no other change. Only occurs in very proton-rich nucleii.
• n Neutron emission. A neutron is emitted from the nucleus.
• SF Spontaneous fission. Only occurs in very heavy elements, which can split into two lighter nucleii, and emit neutrons.
• CD Cluster decay is somewhat between alpha decay and fission. Occurs when a nucleus splits into two smaller nucleii with significantly different masses, such as 223-Ra to 14-C + 209-Pb.
