What elements does thulium bond with?

What elements does thulium bond with?

Thulium metal reacts with all the halogens to form thulium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively thulium(III) bromide, TmF3, thulium(III) chloride, TmCl3, thulium(III) bromide, TmBr3, and thulium(III) iodide, TmI3.

What elements does yttrium react with?

Yttrium is very reactive towards the halogens fluorine, F2, chlorine, Cl2 bromine, Br2, and iodine, I2, and burns to form the trihalides yttrium(III) fluoride, YF3 , yttrium(III) chloride, YCl3, yttrium(III) bromide, YBr3, and yttrium(III) iodide, YI3 respectively.

What common compounds is thulium found in?

Thulium forms no commercially important compounds. Some of thulium’s compounds include: thulium oxide (Tm2O3), thulium fluoride (TmF3) and thulium iodide (TmI3).

What makes thulium unique?

Thulium is a lanthanide element, it has a bright silvery-gray luster and can be cut by a knife. It is the least abundant of the rare earths and its metal is easy to work. It slowly tarnishes in air, but is more resistant to oxidation than most rare-earth elements.

Is thulium a element?

Thulium (Tm), chemical element, a rare-earth metal of the lanthanide series of the periodic table.

What is the element family of thulium?

Lanthanides

What can yttrium do?

A soft, silvery metal. 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.

Is yttrium a transition element?

Yttrium is a chemical element with symbol Y and atomic number 39. Classified as a transition metal, Yttrium is a solid at room temperature.

What is thulium in the periodic table?

thulium (Tm), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Thulium is a strong paramagnet above 56 K (−217 °C, or −359 °F).

Is thulium a compound?

Thulium forms no commercially important compounds. Some of thulium’s compounds include: thulium oxide (Tm2O3), thulium fluoride (TmF3) and thulium iodide (TmI3). Because of the relatively high price of the metal, thulium has not yet found many practical applications.

What are 5 interesting facts about thulium?

Facts About Thulium

• Atomic Number: 69 Atomic Symbol: Tm Atomic Weight: 168.93421 Melting Point: 2,813 F (1,545 C) Boiling Point: 3,542 F (1,950 C)
• Word origin: Thulium is named for Thule, the earliest name for Scandinavia.
• Discovery: This rare earth was discovered by Sweedish chemist Per Teodor Cleve in 1879.

How did thulium get its symbol?

Cleve named the oxide thulia and its element thulium after Thule, an Ancient Greek place name associated with Scandinavia or Iceland. Thulium’s atomic symbol was once Tu, but this was changed to Tm.

What is thulium in the periodic table of elements?

What is Thulium? 1 Thulium is a chemical element having an atomic number 69 with the symbol Tm, discovered by Theodor Cleve in the year 1879. 2 It is the thirteenth element in the lanthanide series in the periodic table. 3 The element is barely traced purely in nature but it is traced in minute amounts in minerals with other rare earth metals.

Is there anything you can do with thulium?

For a long time thulium was a Cinderella substance. There was nothing you could do with thulium that couldn’t be done better and cheaper with one of the other elements. It looked likely that it would be consigned to the dustbin of useless chemical substances.

What did John Cleve call the compound of thulium?

Cleve realized that erbium was not really an element, but was made up of three other substances. Cleve called these substances erbium, holmium, and thulium. The substance Cleve called thulium was not pure thulium, but a compound of thulium combined with other elements.

How does thulium react with air and water?

Thulium is a reactive metal. When exposed to air and water it is tarnished slowly. It speedily burns at 150 O C and form thulium (lll) oxide. It is electropositive and react slowly with cold water and quickly with hot water and formed thulium hydroxide.
