Thallium Element Facts The metal can easily be cut with a knife. It usually exists in the monovalent state, Tl + , in its compounds. In the presence of water, the poisonous thallium hydroxide (TlOH) is formed. Thallium dissolves slowly in hydrochloric acid and dilute sulfuric acid and dissolves rapidly in nitric acid.

Europium Element Facts / Chemistry Uses of Europium. Europium oxide (europia) is widely used as a doping agent in phosphors in television sets and computer monitors: valency three europium produces a red radiance and valency two europium produces a blue radiance. When both valencies are combined a white light is produced which is used in compact fluorescent bulbs.

Thallium However, the +1 state, which is far more prominent in thallium than the elements above it, recalls the chemistry of alkali metals, and thallium(I) ions are found geologically mostly in potassium-based ores, and (when ingested) are handled in many ways like potassium ions (K+) by ion pumps in living cells.

Thallium Soluble thallium salts (many of which are nearly tasteless) are highly toxic in quantity, and were historically used in rat poisons and insecticides. Use of these compounds has been restricted or banned in many countries, because of their nonselective toxicity. Notably, thallium poisoning results in hair loss.hallium is found in the minerals crookesite TlCu 7 Se 4, hutchinsonite TlPbAs 5 S 9, and lorandite TlAsS 2. Thallium also occurs as a trace element in iron pyrite, and thallium is extracted as a by-product of roasting this mineral for the production of sulfuric acid.

Tantalum: uses Tantalum wires were those used first for light bulbs (now tungsten is preferred). The metal is immune to body liquids and the body tolerates the metal well. Therefore, tantalum has widespread use for surgical use. For instance, it can be used in sutures and as cranial repair plates. The metal is used in the electronics industry for capacitors. The oxide is used to make special glass with a high index of refraction for camera lenses.

thallium Historical Examples. 1  We will now remove the thallium and put a bit of silver in its place. 2  The simplest curve of this type will be obtained when only one compound is formed, as is the case with mercury and thallium. 3  The thallium papers show that the greatest effect is in the daytime, the iodide papers that it is at night.

It's Elemental He named the new element that was producing the green line thallium, after the greek word for 'green twig', thallos. He isolated samples of thallium the next year.Thallium is found in the minerals crooksite (CuThSe), lorandite (TlAsS 2) and hutchinsonite ((Pb, Tl) 2 As 5 S 9), but is usually obtained as a byproduct of the production of sulfuric acid or as a byproduct of refining zinc or lead.istory and Uses: Thallium was discovered spectroscopically by Sir William Crookes, an English chemist, in 1861. Crooks had obtained the sludge left over from the production of sulfuric acid (H 2 SO 4) from a friend.

What do you use europium for? It's also been used in the creation of infrared absorbing automotive glass. Europium's compound, Europium Oxide, is often used as a phosphor activator. Europium's other two roles are also involved with phosphors. Europium is used in the production of phosphors for the creation of small lasers.But perhaps what Europium is known best for is the production of the red phosphors that are found in all color television screens.uropium is used in the production of phosphors for the creation of small lasers.

Thallium 203 Tl and 205 Tl are the only stable isotopes and 204 Tl is the most stable radioisotope with a half-life of 3.78 years. Thallium-202 (half life 12.23 days) can be made in a cyclotron while thallium-204 (half life 3.78 years) is made by the neutron activation of stable thallium in a nuclear reactor. The lead-201 can be produced in a cyclotron by the bombardment of thallium with protons or deuterons by the (p,3n) and (d,4n) reactions. 2  combined with sulfur or selenium and arsenic, thallium has been used in the production of high-density glasses that have low melting points in the range of 125 and 150 °C.
