Nuclear Chemistry

Nuclear chemistry is the study of chemical reactions involving changes in the number of protons and neutrons within each atom. With Wolfram|Alpha, one can explore the nuclear structure and properties of nuclides, such as the symbols, mass and neutron numbers, mass defects, binding energies and cosmic origins.
Nuclide Symbols

Build the nuclide symbol.

Write the nuclide symbol:

What is the nuclide symbol for oxygen-14
fluorine-19 full symbol
full symbol U-235

Write the abbreviated nuclide symbol:

What is the abbreviated symbol for tritium?
carbon-14 symbol
brief symbol lead-207
