Where do you find ytterbium?
Ytterbium is found with other rare-earth elements in several rare minerals. It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia.
How common is the element ytterbium?
Ytterbium is the 44th most abundant element in the Earth’s crust. It is one of the more common rare earths, present at about 2.7 to 8 parts per million in the crust. It is common in the mineral monazite.
Where is ytterbium usually found?
What is the most common isotope of erbium?
Naturally occurring erbium is composed of 6 stable isotopes, Er-162, Er-164, Er-166, Er-167, Er-168, and Er-170 with Er-166 being the most abundant (33.6% natural abundance).
Where is ytterbium on the periodic table?
lanthanide
Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state.
What is ytterbium mass number?
173.04 uYtterbium / Atomic mass
What is the most abundant stable isotope of ytterbium?
The isotopes of ytterbium range in atomic weight from 147.967 u ( 148 Yb) to 180.9562 u ( 181 Yb). The primary decay mode before the most abundant stable isotope, 174 Yb is electron capture, and the primary mode after is beta emission.
What is ytterbium?
Ytterbium is a chemical element with symbol Yb and atomic number 70. Classified as a lanthanide, Ytterbium is a solid at room temperature.
What is the electrical resistance of ytterbium at high pressure?
The electrical resistance increases tenfold as the pressure is increased to 39,000 atm and drops to about 10% of its standard temperature-pressure resistivity at a pressure of 40,000 atm. Natural ytterbium is a mixture of seven stable isotopes. Seven other unstable isotopes are known.
What is the valence state of ytterbium?
Ytterbium can also exist in the +2 valence state; its compounds are powerful reducing agents and it is capable of reducing water to hydrogen gas. Ytterbium is named after the town of Ytterby near Stockholm in Sweden, and makes up the fourth element to be named after this town, the others being of course yttrium, terbium and erbium.
