See more Europium products. Europium (atomic symbol: Eu, atomic number: 63)is a Block F, Group 3, Period 6 element with an atomic radius of 151.964. Europium Bohr ModelThe number of electrons in each of Europium's shells is 2, 8, 18, 25, 8, 2 and its electron configuration is [Xe]4f7 6s2. The europium atom has an atomic radius of 180 pm and a Van der Waals radius of 233 pm. Europium was discovered by Eugène-Anatole Demarçay in 1896, however, he did not isolate it until 1901. Europium was named after the continent of Europe.Elemental Europium Picture Europium is a member of the rare earth series of metals in its elemental form, it has a silvery-white appearance but it is rarely found without oxide discoloration. Europium is found in many minerals including bastnasite, monazite, xenotime and loparite. It is not found in nature as a free element.

The number of electrons in each of Iodine's shells is 2, 8, 18, 18, 7 and its electron configuration is [Kr] 4d10 5s2 5p5. The iodine atom has a radius of 140 pm and a Van der Waals radius of 198 pm. In its elemental form, iodine has a lustrous metallic gray appearance as a solid and a violet appearance as a gas or liquid solution. Elemental IodineIodine forms compounds with many elements, but is less active than the other halogens. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulfide. Iodine compounds are important in organic chemistry and very useful in the field of medicine. Iodine was discovered and first isolated by Bernard Courtois in 1811. The name Iodine is derived from the Greek word "iodes" meaning violet.

Strontium Bohr ModelThe number of electrons in each of Strontium's shells is [2, 8, 18, 8, 2] and its electron configuration is [Kr] 5s2. The strontium atom has a radius of 215 pm and a Van der Waals radius of 249 pm. Strontium was discovered by William Cruickshank in 1787 and first isolated by Humphry Davy in 1808. In its elemental form, strontium is a soft, silvery white metallic solid that quickly turns yellow when exposed to air. Elemental StrontiumCathode ray tubes in televisions are made of strontium, which are becoming increasingly displaced by other display technologies pyrotechnics and fireworks employ strontium salts to achhieve a bright red color. Radioactive isotopes of strontium have been used in radioisotope thermoelectric generators (RTGs) and for certain cancer treatments. In nature, most strontium is found in celestite (as strontium sulfate) and strontianite (as strontium carbonate). Strontium was named after the Scottish town where it was discovered.
