For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element.

Lanthanides are rare-earth metals grouped chemically because they possess partially filled inner shells of electrons (4f and 5d subshells). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1.
