Gadolinium is the chemical element with atomic number 64 and symbol . It is a lanthanide. The ion has seven unpaired 4f electrons, giving it strong paramagnetism. This connects atomic electron configuration with magnetic behavior and with the effect of coordinated gadolinium on nearby nuclear-spin relaxation.[ref]
A gadolinium isotope with a very large thermal-neutron absorption cross section. Its isotope-specific cross section is not the same as the isotope-averaged value for natural gadolinium.
