Is terbium a rare earth metal?
Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogengas.
What is special about terbium?
A soft, silvery metal. Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, all used in solid-state devices. It is also used in low-energy lightbulbs and mercury lamps. An alloy of terbium, dysprosium and iron lengthens and shortens in a magnetic field.
Where is terbium found in the world?
It is never found in nature as free element, but is is contained in many minerals. The most important ore are monazite, bastnasite and cerite. The main mining areas are China, USA, India, Sri Lanka, Brazil and Australia and reserves fo terbium are estimated to be around 300.000 tonnes.
What are the isotopes of terbium?
Isotopes. Naturally occurring terbium is composed of 1 stable isotope, 159-Tb. 33 radioisotopes have been characterized, with the most stable being 158-Tb with a half-life of 180 years, 157-Tb with a half-life of 71 years, and 160-Tb with a half-life of 72.3 days.
How much of terbium exists in the world?
Terbium is one of the least abundant of the rare earths; its abundance in Earth’s crust is about the same as thallium. The only isotope occurring in ores is terbium-159. A total of 36 (excluding nuclear isomers) radioactive isotopes of terbium have been identified….terbium.

Is Terbium used in medicine?
One radioactive isotope, terbium-149, is used in medicine. The isotope is injected directly into cancer cells in a patient’s body. The radiation given off kills the cancer cells.

Is terbium used in cell phones?
Terbium. Terbium again is one of the many elements in the phone (It`s symbol is “Tb”). Terbium is used in the circuit boards to transport power. Gold is another element out of many too (It`s element symbol is “Au”).
How was terbium discovered?
Terbium was first identified by Swedish chemist Carl Gustaf Mosander in 1843, who detected its oxide it as an impurity in yttria (mainly yttrium oxide, Y₂O₃). Though it was discovered as an element in 1843, pure terbium was not isolated until ion exchange methods were introduced in the 20thcentury.
What is terbium worth?
Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams. Dysprosium, the cheapest of the rare-earth elements discovered, only costs $450 per 100 grams.
What do you need to know about terbium element?
Terbium is a lanthanide element. Know everything about Terbium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure. Terbium is a chemical element with symbol Tb and atomic number 65. It is a silvery-white rare earth metal that is malleable, ductile and soft enough to be cut with a knife.
How did Carl Mosander discover the element terbium?
Terbium was first isolated in 1843 by the Swedish chemist Carl Mosander at Stockholm. He had already investigated cerium oxide and separated a new element from it, lanthanum, and now he focussed his attention on yttrium, discovered in 1794, because he thought this too might harbour another element.
Is the element terbium the same as the lanthanides?
You see, although a common perception is that lanthanides all have the same chemistry, and some have even described them as ‘boring’, each element has its own unique and special characteristics. Terbium, element number 65, is no different and lies in the middle of the lanthanide series in between gadolinium and dysprosium.
How are iron, dysprosium and terbium used in everyday life?
An alloy of terbium, dysprosium and iron lengthens and shortens in a magnetic field. This effect forms the basis of loudspeakers that sit on a flat surface, such as a window pane, which then acts as the speaker. Terbium has no known biological role.
