- Its Elemental - The Element Tellurium
Tellurium is a semiconductor and is frequently doped with copper, tin, gold or silver Tellurium is also used to color glass and ceramics and is one of the primary ingredients in blasting caps Tellurium is primarily used as an alloying agent Small amounts of tellurium are added to copper and stainless steel to make them easier to machine and

- Its Elemental - The Element Thallium
Rather than seeing the yellow spectral lines produced by tellurium, he observed a bright green line that no one had ever seen before He named the new element that was producing the green line thallium, after the greek word for 'green twig', thallos
- Its Elemental - The Element Gold
An attractive and highly valued metal, gold has been known for at least 5500 years Gold is sometimes found free in nature but it is usually found in conjunction with silver, quartz (SiO 2), calcite (CaCO 3), lead, tellurium, zinc or copper There is roughly 1 milligram of gold dissolved in every ton of seawater, although extracting it currently costs more than the gold is worth It has been
- Its Elemental - The Element Selenium
Originally believing the material was tellurium, Berzelius eventually realized that it was actually a previously unknown element Selenium occurs in minerals such as eucairite (CuAgSe), crooksite (CuThSe) and clausthalite (PbSe), but these minerals are too rare to use as a major source of selenium
- Its Elemental - The Element Antimony
Antimony has been known since ancient times It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3) Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds He published his findings in 1707 Antimony makes up about 0 00002% of the earth's crust Antimony is a brittle metal
