What the heck is element Yb?
?

• And why did I choose such an obscure element?

WellChem is hard and I like to be consistent...

Element Yb is Ytterbium. (i-TUR-bi-em)

Basics facts of Ytterbium

• Ytterbium is a metal in the lanthanoid family.
• It has 70 protons, 103 neutrons, and 70
  electrons. (in its most stable isotope)
• 819oC and 1198oC are, respectively, its melting
  and boiling point.
• It has very few practical uses compared to other
  elements

The few uses of Ytterbium

• Ytterbium is often used as a doping agent for
  fiber optic cable. Doping is the process of
  introducing impurities into a pure substance.
  This fiber optic cable is used in lasers to
  produce infrared energy and for

lt---Doped fiber optic cable. These cables will
help develop high powered green lasers.

The few uses of Ytterbium

• Ytterbium metal has uses in improving the grain
  refinement, strength, and other mechanical
  properties of stainless steel. Some Ytterbium
  alloys are used in dentists offices as well.
• One isotope is reported to have been used as a
  radiation source substitute for a portable X-ray
  machine where electricity is unavailable.
• Ytterbium helps convert infrared energy into
  electrical energy in solar cells.

Common Forms of Ytterbium

• One form of the forms of this elements that occur
  naturally is Monazite. All kinds of rare earth
  metals are extracted from this compound. Some
  include Thorium, Lanthanum, Cerium and of course,
  Ytterbium.

8
Other common forms of Ytterbium

• This is Xenotime and it is also an important
  source of rare earth metals. Disprosium, Erbium,
  Terbium, Ytterbium, Thorium, and even Uranium can
  be extracted from this compound.

You should buy Ytterbium!

• Well, to be honest, you shouldnt. This element
  is known to cause irritation to eyes and skin.
  In addition, it may be teratogenic. This element
  is usually treated as highly toxic even though
  studies indicate it to be otherwise.
• Hey...better safe then sorry.
