There are different isotopes of Lutetium. The metal is easily Lutetium (177Lu) chloride is produced by irradiation of 176Lu with neutrons. Answered By . Upvote(0) How satisfied are you with the answer? 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. It is the heaviest and hardest of the rare earth elements. Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The core of lutetium , the Lu-142, with 71 protons and 71 neutrons (odd number) breaks the high symmetry giving only one stable isotope. The maximum beta energy for the decay of 177Lu to 177Hf is 0.497 MeV. Atomic mass of Lutetium is 174.967 u. C. 1 7 5, 1 0 4 and 7 1. Which one… Lutetium is a lanthanide element. D. 7 1, 1 0 4 and 7 1. Solution for The element lutetium has two naturally occurring isotopes: Lu and Lu. It is sometimes used in metal alloys and as a catalyst in various processes Among such side effects are abdominal pain, nausea, vomiting, and rarely – hair loss. Lutetium is found with almost all rare-earth metals, but is very difficult to separate from other elements. Mass number (A) of an element is equal to sum of protons and neutrons present in its nucleus. In its pure form, lutetium metal is silvery white and stable in air. Total number of protons in the nucleus is called the ... Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure. Number of Protons: 78: Number of Neutrons: 117: Number of Electrons: 78: Melting Point: 1772.0° C: Boiling Point: 3827.0° C: Density: 21.45 grams per cubic centimeter: Normal Phase: Solid: Family: Transition Metals: Period: 6: Cost: Varies greatly: $561 per ounce $4700 per 100 grams .
