Breathing the dust can cause lung embolisms, and accumulated exposure damages the liver. Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure.

[9] The metal is obtained through electrolysis of its halide salts. Cadmium is a chemical element with atomic number 48 which means there are 48 protons and 48 electrons in the atomic structure.
Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. Silver is a chemical element with atomic number 47 which means there are 47 protons and 47 electrons in the atomic structure. Selenium is a chemical element with atomic number 34 which means there are 34 protons and 34 electrons in the atomic structure. The chemical symbol for Neodymium is Nd. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars. For example, it can decompose a nerve agent, shown on tile on the right. In 1885 Carl Welsbach, who had discovered ‘didymium’ 14 years earlier, realized it was actually a mixture of two entirely new elements. Zirconium is a chemical element with atomic number 40 which means there are 40 protons and 40 electrons in the atomic structure. Polonium is a rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. Thorium is commonly found in monazite sands (rare earth metals containing phosphate mineral). All of the remaining radioactive isotopes have half-lives that are shorter than eleven days, and the majority of these have half-lives that are shorter than 70 seconds.

Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. A list of reference sources used to compile the data provided on our periodic table of elements can be found on the main periodic table page.
Neodymium behaves in a complex magnetic way that had not been seen before in a periodic table element.[28][29]. In combination with gold or selenium, red colors are produced. Neodymium usually exists as a trivalent ion, Nd3+, in its compounds. Commercially it is extracted from monazite and bastnaesite by ion exchange and solvent extraction processes. Although neodymium is classed as a rare earth, it is a fairly common element. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Neodymium belongs to the lanthanide series and is a rare-earth element. Nickel is a silvery-white lustrous metal with a slight golden tinge. Radon is a radioactive, colorless, odorless, tasteless noble gas. Compact Fluorescent Lights (CFLs): Are They Worth the Switch?

Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. Some neodymium compounds have colors that vary based upon the type of lighting. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. It is fairly soft and slowly tarnishes in air.
