Gadolinium is a Block F, Group 3, Period 6 element with an atomic radius of 157.25. The number of electrons in each of Gadolinium’s shells is [2, 8, 18, 25, 9, 2] and its electron configuration is [Xe] 4f7 5d1 6s2. The gadolinium atom has a radius of 180 pm and a Van der Waals radius of 237 pm.
Gadolinium was discovered by Jean Charles Galissard de Marignac in 1880 and first isolated by Lecoq de Boisbaudran in 1886. In its elemental form, gadolinium has a silvery-white appearance. Gadolinium is a rare earth or lanthanide element that possesses unique properties advantageous to specialized applications such as semiconductor fabrication and nuclear reactor shielding.Â
It is utilized for both its high magnetic moment (7.94μ B) and in phosphors and scintillator crystals. When complexed with EDTA ligands, it is used as an injectable contrast agent for MRIs. The element is named after the Finnish chemist and geologist Johan Gadolin.
Gallium:
Gallium is a Block P, Group 13, Period 4 element with an atomic weight of 69.723.The number of electrons in each of Gallium’s shells is 2, 8, 18, 3 and its electron configuration is [Ar] 3d10Â 4s2Â 4p1. The gallium atom has a radius of 122.1 pm and a Van der Waals radius of 187 pm.Â
Gallium was predicted by Dmitri Mendeleev in 1871. It was first discovered and isolated by Lecoq de Boisbaudran in 1875. In its elemental form, gallium has a silvery appearance. Gallium is one of three elements that occur naturally as a liquid at room temperature, the other two being mercury and cesium.
Gallium does not exist as a free element in nature and is sourced commercially from bauxite and sphalerite. Currently, gallium is used in semiconductor devices for microelectronics and optics. The element name originates from the Latin word ‘Gallia’, the old name of France, and the word ‘Gallus,’ meaning rooster.
