How is ytterbium 169 made?
Ytterbium 169 is produced by thermal-neutron bombardment of enriched stable ytterbium 168 resulting in a specific activity of greater than 100 mCi/mg. The product contains less than 1 per cent of ytterbium 175 which emits beta and gamma rays and has a 4.2-day half-life.What is the difference between yttrium and ytterbium?
Yttrium is a chemical element having the symbol Y and atomic number 39, while Ytterbium is a chemical element having the symbol Yb and atomic number 70. The key difference between Yttrium and Ytterbium is that natural yttrium is non-radioactive, whereas ytterbium is usually radioactive.
Where is ytterbium found?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.
Article first time published onWhich atom contains exactly 16 neutrons?
if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
What is ytterbium used for?
Ytterbium has few uses. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier. One of ytterbium’s isotopes is being considered as a radiation source for portable X-ray machines.
What element family is ytterbium?
Ytterbium belongs to the lanthanide family. The lanthanides make up Row 6 of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The lanthanides are also known as the rare earth elements.
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.
What is the density of the element ytterbium?

What is the 70th element?
Ytterbium is a chemical element with symbol Yb and atomic number 70.
Is ytterbium a noble gas?
The ground state electronic configuration of Neutral Ytterbium atom is [Xe] 4f14 6s2. The portion of Ytterbium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Xe].
What does ytterbium react with?
Ytterbium metal reacts with all the halogens to form ytterbium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively ytterbium(III) bromide, YbF3, ytterbium(III) chloride, YbCl3, ytterbium(III) bromide, YbBr3, and ytterbium(III) iodide, YbI3.
What is the half-life of ytterbium 169?
