PHONETICS

IDENTIFICATION

Lutetium is a silvery white metal, which resists corrosion in dry, but not in moist air. Lutetium is not a particularly abundant element, though significantly more common than silver in the earth’s crust; it has few specific uses. Lutetium-176 is a relatively abundant (2.5%) radioactive isotope with a half-life of about 38 billion years, and so used to determine the age of meteorites.

ELEMENT BRIEF
