Lutetium is a silvery-white metallic element of the lanthanide series that is used in nuclear technology. It is the last element in the lanthanide series, and it is traditionally counted among the rare earths. Its atomic number 71; atomic weight Its radioactive isotope is used in determining the age of meteorites. The honour of discovering lutetium went to Georges Urbain at the Sorbonne in Paris, because he was the first to report it. The story began with the discovery of yttrium in from which several other elements — the rare earths aka lanthanoids — were to be separated, starting with erbium in and ending with lutetium in Indeed James, who was at the University of New Hampshire, was ahead of Urbain and had extracted quite a lot of the new metal, but he delayed publishing his research.
Lutetium is a chemical element with the symbol Lu and atomic number It is a silvery white metal , which resists corrosion in dry air, but not in moist air. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths.
Tamjwh talk , 18 October UTC.
