Acerca de Gadolinio

Valued in medicine as an MRI contrast agent, gadolinium (Gd) enhances the clarity of magnetic-resonance images by altering the magnetic behavior of nearby tissue. Element 64 is a lanthanide in period 6 of the f-block, with an atomic mass of 157.25, the electron configuration [Xe] 4f⁷ 5d¹ 6s², and a Pauling electronegativity of 1.2. It possesses the highest thermal-neutron absorption cross-section of any stable element, which makes it useful in nuclear-reactor shielding and control. Gadolinium also displays notable magnetic properties near room temperature. The silvery metal is solid at standard conditions.
