What does terbium look like?
Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, and ductile. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.
What type of element is terbium?
Terbium, element number 65, is no different and lies in the middle of the lanthanide series in between gadolinium and dysprosium. It is one of the rarer rare earth elements, although it is still twice as common as silver in the Earth’s crust.

Is terbium used in cell phones?
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”).
Where is terbium found?
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 is the meaning of terbium?
Definition of terbium : a metallic element of the rare-earth group with atomic number 65 that occurs naturally only in combination and that is used especially in alloys for electronic equipment and as a green phosphor (see phosphor sense 2) in electronic displays — see Chemical Elements Table.

What is the flammability of terbium?
Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, sparks or flame. May react with water under fire conditions to liberate flammable hydrogen gas. May emit fumes of terbium oxide under fire conditions.
Where is terbium found in the world?
What is terbium worth?
The metals are expensive, making the find extremely valuable, with some estimates putting the value of the island’s rare earth oxide alone at approximately $500 billion. Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams.
When was terbium found?
What is a terbium atom?
Please visit the Terbium element page for information specific to the chemical element of the periodic table. More… Terbium atom is a lanthanoid atom and a f-block element atom. An element of the rare earth family of metals. It has the atomic symbol Tb, atomic number 65, and atomic weight 158.92.
What is the transformation temperature of terbium in allotropes?
Terbium exists in two crystal allotropes with a transformation temperature of 1289 °C between them. The 65 electrons of a terbium atom are arranged in the electron configuration [Xe]4f 9 6s 2; normally, only three electrons can be removed before the nuclear charge becomes too great to allow further ionization,…
What fraction of terbium is colorless in solution?
“Erbia” (containing what is now known as terbium) originally was the fraction that was essentially colorless in solution. The insoluble oxide of this element was noted to be tinged brown. Later workers had difficulty in observing the minor colorless “erbia”, but the soluble pink fraction was impossible to miss.
Does terbium react with sulfuric acid?
Terbium metal is an electropositive element and oxidizes in the presence of most acids (such as sulfuric acid), all of the halogens, and even water. Terbium also oxidizes readily in air to form a mixed terbium (III,IV) oxide: 3.
