Europium ignites in air at about 150 °C to 180 °C. These numbers may well differ considerably from, say, single bond energies in a solid. Europium is the most reactive rare-earth element. Scientists must use great care in handling the metal. It is element atomic number 63, with the symbol Eu. Its boiling point is 1529 O C. Get periodic table facts on the chemical and physical properties of the element element europium, which it atomic number 63. chemical properties, health and environmental effects of erbium. The number of electrons in each of Europium's shells is 2, 8, 18, 25, 8, 2 and its electron configuration is [Xe]4f7 6s2. Experimental Physico-chemical Properties. These particles are insoluble in water, and moderately soluble in strong mineral acids. Thermal properties of materials refer to the response of materials to changes in their temperature and to the application of heat. A team of researchers from Russia, the United States, and China led by Skoltech Professor Artem R. Oganov has discovered an unexpected very complex europium hydride, Eu8H46. 63. The chemical element Europium, obviously named after the continent, has atomic number 63 the symbol Eu. Europium chemical symbol is Eu. When both valencies are combined a white light is produced which is used in compact fluorescent bulbs. It is about as hard as lead and quite ductile. It also reacts strongly with oxygen in the air, catching fire spontaneously. Electronegativity according to Pauling Europium is the most reactive of the rare earth elements; it rapidly oxidizes in air, and resembles calcium in its reaction with water; deliveries of the metal element in solid form, even when coated with a protective layer of mineral oil, are rarely shiny.
