Know everything about Lutetium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure. Other articles where Lutetium-175 is discussed: lutetium: …consists of two isotopes: stable lutetium-175 (97.4 percent) and radioactive lutetium-176 (2.6 percent, 3.76 × 1010-year half-life). Lutetium oxide is used in catalysts in the petroleum industry and Lu -177 the isotope is used in cancer treatments due to its radioactivity. Answer. Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure. The most stable isotope is Lu-174 with a half-life of 3.3 years. 71 Lu (Lutetium) Appearance: Hard, Silvery white Mass number: 175 Atomic weight: 174.9668 g/mol Atomic number: 71 Electrons: 71 Protons: 71 Neutrons: 104 The boiling point of lutetium is 3675 degrees Kelvin or 3402.85 degrees Celsius or degrees Celsius. Isotopes are atoms of the same element that have different masses because they have different numbers of neutrons. This element is used in metal alloys, and as a catalyst in various processes.

This will help us to improve better. The radioactive isotope is used to determine the age of meteorites relative to that of Earth. Please contact us via request a Lutetium-176 isotope quote BuyIsotope.com to order Lutetium-176 isotope, to get Lutetium-176 price and to buy Lutetium-176 isotope. Lutetium (Lu), chemical element, a rare-earth metal of the lanthanide series of the periodic table, that is the densest and the highest-melting rare-earth element and the last member of the lanthanide series. Remarkable results have been obtained with optogenetics, although the need for genetic modification is an important limitation of these approaches. Atomic mass of Lutetium is 174.967 u. in an atom) present in an atom. Atomic Number of Lutetium. Thus, the radioactivity (A) of the desired atoms at time t … There are two natural isotopes, 1 of which is stable one. The chemical symbol for Lutetium is Lu. Lutetium’s melting point is 1925 degrees Kelvin or 1652.85 degrees Celsius or degrees Celsius. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. Holmium is a relatively soft and malleable silvery-white metal.Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. Lutetium is a chemical element with the symbol Lu and atomic number 71. The nucleus is composed of protons and neutrons. There are different isotopes of Lutetium. The Lu isotope has a mass of 174.940 amu and is 97.41% abundant. n p = n e = 7 1 n p + n n = 1 7 5 n n = 1 7 5 − 7 1 = 1 0 4 Option D is correct. Lutetium (chemical symbol Lu, atomic number 71) is a silvery white, metallic element that usually occurs in association with yttrium. where N 1 is the number of activated atoms; φ, neutron flux in n cm − 2 s − 1; σ, neutron activation cross-section in barn (10 − 24 cm 2); N T, the total number of atoms present in the target; and λ, the decay constant (0.693/t 1/2). toppr. Radioisotopes are commonly used to treat cancer. D. 7 1, 1 0 4 and 7 1. The nucleus consists of 71 protons (red) and 104 neutrons (orange).
