What is the symbol for yttrium?
Y
What is Yttriums melting point?
2,779°F (1,526°C)
What is yttrium used for?
Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals.
Is yttrium rare?
Abundance. Yttrium is found in most rare-earth minerals, it is found in some uranium ores, but is never found in the Earth’s crust as a free element. About 31 ppm of the Earth’s crust is yttrium, making it the 28th most abundant element, 400 times more common than silver.
Is yttrium dangerous?
Yttrium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Yttrium can also cause cancer with humans, as it enlarges the chances of lung cancer when it is inhaled.
How common is yttrium?
The Earth’s crust is made up of about thirty-one parts per million yttrium. That makes yttrium the 28th most common element. Yttrium is around 400 times more common than silver.
What element breaks down into yttrium 90?
Strontium- 90 decays to yttrium-90, which in turn decays to stable zirconium. The isotopes of strontium and yttrium emit beta particles as they decay.
How much does yttrium cost?

Is ytterbium radioactive?
Ytterbium also has ten radioactive isotopes. Ytterbium-169 is one such radioactive isotope that gives off gamma radiation similar to X rays.
Why is lutetium so expensive?
The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium. Atoms of synthetic elements cost millions of dollars to produce.
Does the human body use lutetium?
Lutetium has no biological role but is said to stimulate the metabolism.
Is lutetium man made?
Discovery of Lutetium. Lutetium was the last natural rare earth element to be discovered. The synthetic rare earth promethium was produced later in the laboratory from uranium fission products. Lutetium was independently discovered by Carl Auer von Welsbach, Charles James, and Georges Urbain.
Where is lutetium found?
Lutetium is never found in nature as the free element. Lutetium is found in the ores monazite sand [(Ce, La, etc.) PO4] and bastn°site [(Ce, La, etc.)(…Abundances of lutetium in various environments.

Is lutetium poisonous or hazardous?
Lutetium is mildly toxic by ingestion, but its insoluble salts are non-toxic. Like other rare-earth metals lutetium is regarded as having a low toxicity rating but it and its compounds should be handled with care.
Who found lutetium?
Carl Auer von Welsbach
What color is element lutetium?
silvery white
Is terbium a metal?
A soft, silvery metal. Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, all used in solid-state devices.
