Gadolinium Bohr ModelThe 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. Elemental Gadolinium PictureIt 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.

See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.

Terbium (atomic symbol: Tb, atomic number: 65) is a Block F, Group 3, Period 6 element with an atomic radius of 158.92535.Terbium Bohr Model The number of electrons in each of Terbium's shells is [2, 8, 18, 27, 8, 2] and its electron configuration is [Xe]4f9 6s2. The terbium atom has a radius of 177 pm and a Van der Waals radius of 221 pm.Terbium was discovered and first isolated by Carl Gustaf Mosander in 1842. In its elemental form, terbium is a silvery-white soft metal. Terbium is found in cerite, gadolinite, and monazite. It is not found in nature as a free element. Elemental TerbiumTerbium compounds are brightly fluorescent, and a majority of the world's terbium supply is used for creating green phosphors that enable trichromatic lighting technology. It is also frequently used as a dopant for crystalline solid-state devices and fuel cell materials. It is named after Ytterby, the town in Sweden where it was discovered.
