Experimental Physico-chemical Properties. Europium is a chemical element with atomic number 63 which means there are 63 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. What is Europium. Europium oxide nanoparticles appear in white powder form. Chemical Properties Being the most reactive lanthanide, it instantly oxides in air and reacts with it to form europium oxide. It Ignites quickly in air at about 150 o C to 180 o C. With the development of ion-exchange techniques and special processes, the cost of the metal has been greatly reduced in recent years. Atomic mass. Because of its high reactivity, solid europium rarely looks shiny. Its melting point is 826 O C which is the second lowest melting point. it reacts quickly with water to give off hydrogen. chemical properties, health and environmental effects of europium.
