The two chemists, William Crookes and Claude-Auguste Lamy, discovered thallium independently in 1861 by the newly developed method of flame spectroscopy. Both discovered the new element in residues of sulfuric acid production. Approximately 60–70% of thallium production is used in the electronics industry, and the rest is used in the pharmaceutical industry and in glass manufacturing. It is also used in infrared detectors. It is highly toxic and was used in rat poisons and insecticides. Its use has been cut back or eliminated in many countries because of its nonselective toxicity.

Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world. It was discovered in 1828 and named after Thor, the Norse god of thunder. It is a component of the magnesium alloy called Mag-Thor, used in aircraft engines and imparting high strength and creep resistance at elevated temperatures. Thoriated magnesium was used to build the CIM-10 Bomarc missile, although concerns about radioactivity have resulted in several missiles being removed from public display. Thorium is also used as an alloying agent in gas tungsten arc welding to increase the melting temperature of tungsten electrodes and improve arc stability. Thorium dioxide and thorium nitrate were used in mantles of portable gas lights, including natural gas lamps, oil lamps and camping lights. These mantles glow with an intense white light when heated in a gas flame, and its color could be shifted to yellow by addition of cerium. Thorium dioxide is a material for heat-resistant ceramics and also has been used as a catalyst in the conversion of ammonia to nitric acid, in petroleum cracking and in producing sulfuric acid. Thorium, as well as uranium and plutonium, can be used as fuel in a nuclear reactor and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.

Tin is a main group metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide. It is used to coat other metals to prevent corrosion. It has long been used as a solder in the form of an alloy with lead. Another large application for tin is corrosion-resistant tin plating of steel. Because of its low toxicity, tin-plated metal is also used for food packaging, giving the name to tin cans, which are made mostly of steel. Tin in combination with other elements forms a wide variety of useful alloys. It is most commonly alloyed with copper. Window glass is most often made via floating molten glass on top of molten tin in order to make a flat surface. Tin(II) fluoride is added to some dental care products as stannous fluoride. Of all the chemical compounds of tin, the organotin compounds are most heavily used. The major commercial application of organotin compounds is in the stabilization of PVC plastics. Organotin compounds can have a relatively high toxicity, which is both advantageous and problematic. They have been used for their biocidal effects in fungicides, pesticides, algaecides, wood preservatives, and antifouling agents. Some tin reagents are useful in organic chemistry. In the largest application, stannous chloride is a common reducing agent for the conversion of nitro and oxime groups to amines.

Tin (IV) Oxide

Tin (IV) Oxide is a white powder and insoluble in water but soluble in concentrated sulfuric acid, hydrochloric acid. It reacts vigorously with strong reducing agents and is incompatible with chlorine trifluorid. Tin (IV) Oxide has long been used as an opacifier and as a white colorant in ceramic glazes.Its use has been particularly common in glazes for earthenware, sanitary ware and wall tiles; see the articles tin-glazing and Tin-glazed pottery. It can be used as a polishing powder, sometimes in mixtures also with lead oxide, for polishing glass, jewelery, marble and silver. Tin (IV) Oxide coatings are used in glass industry.
