Zirconium is a chemical element with the symbol Zr and atomic number 40. Zirconium alloyed with niobium or tin has excellent corrosion properties . View a scale model of a hydrogen atom.scale model of a hydrogen atom. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. This allows it to combine with other elements and ions in different configurations. More than 90% of zirconium is used in this way. What is Zirconium. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. The chemical symbol for Zirconium is Zr. 40 zirconium (Zr) enhanced Bohr model.png 554 × 556; 51 KB 41 niobium (Nb) enhanced Bohr model.png 554 × 556; 53 KB 42 molybdenum enhanced (Mo) Bohr model.png 554 × 556; 53 KB Zirconium. Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen. Zirconium is alloyed with titanium, niobium and either tin or aluminum, or both. The most common valance charge of zirconium is +4. Zirconium has four valance electrons, with two in the 4d level and two in the 5s level. > Similar to Bohr Model, electrons are limited to certain energy values (energy of an electron is quantized) October 24, 2014 Quantum Mechanical Model of the Atom • There are different kinds of atomic orbitals that differ in ... Zirconium. The high corrosion resistance of zirconium alloys results from the natural formation of a dense stable oxide on the surface of the metal. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Zirconium is a corrosion resistant metal that is used in high performance pumps and valves. The nuclear power industry uses nearly 90% of the zirconium produced each year, which must be nearly free of hafnium. Zirconium and its alloys are widely used as a cladding for nuclear reactor fuels. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold")), the most important source of zirconium. Nuclear reactors can have more than 100,000 metres of zirconium alloy tubing. It has valence charges of +2, +3 and +4. With niobium, zirconium is superconductive at low temperatures and is used to make superconducting magnets. Created Date: Zirconium does not absorb neutrons, making it an ideal material for use in nuclear power stations. Like aluminum, zirconium forms a protective oxide in air. Zirconium is lighter than steel and its hardness is similar to copper. The Bohr Model is probably familar as the "planetary model" of the atom illustrated in the adjacent figure that, for example, is used as a symbol for atomic energy (a bit of a misnomer, since the energy in "atomic energy" is actually the energy of the nucleus, rather than the entire atom). Since it also does not easily absorb neutrons, zirconium is widely used in nuclear reactors. Zirconium is a very strong, malleable, ductile, lustrous silver-gray metal. Its chemical and physical properties are similar to those of titanium. Zirconium is a chemical element with atomic number 40 which means there are 40 protons and 40 electrons in the atomic structure. October 24, 2014. Zirconium is extremely resistant to heat and corrosion.
