![]() ![]() Most other elements have two-letter symbols. TABLE 3.1 Elements with one-letter symbols Symbol Tungsten, discovered in 1783, has the symbol W, for wolframite, the mineral from which tungsten was first isolated. Potassium's symbol, K, comes from kalium, the Latin word for potash. Potassium was discovered in 1807 and named for potash, the substance from which potassium was first isolated. For 12 of these elements, the symbol is the first letter of the name. With the possible exceptions of yttrium (Y) and vanadium (V), you are probably familiar with the names of all elements having one-letter symbols. For 14 of the elements, the symbol consists of one letter. The symbol of an element represents one atom of that element. Seaborg himself was named a Nobel laureate in 1951 in honor of his pioneering work in the preparation of other unknown elements.Įach element has a symbol,one or two letters that represent the element much as your initials represent you. Seaborg was also the first to identify curium at the metallurgical laboratory at the University of Chicago (now Argonne National Laboratory) in 1944. It was first produced in 1950 in the Radiation Laboratory at the University of California, Berkeley, by a team of scientists headed by Glenn Seaborg. Californium is another example of an element named for the place where it was first observed. The small town of Ytterby in Sweden has four elements named for it: terbium, yttrium, erbium, and ytterbium. She was also awarded the Nobel Prize in Chemistry in 1911 for her discovery of the elements polonium (named after Poland) and radium (Latin, radius, "ray"). Marie Curie, a French scientist of Polish birth, was awarded the Nobel Prize in Physics in 1903 for her studies of radioactivity. Curium is named for Marie Curie (1867-1934), a pioneer in the study of radioactivity. Because this element imparts a blue color to a flame, Bunsen named it cesium from the Latin word caesius, meaning "sky blue." Cesium was discovered in 1860 by the German chemist Bunsen (the inventor of the Bunsen burner). The practice of naming an element after one of its properties continues. The Latin name for gold is aurum, meaning "shining dawn." The Latin name for mercury, hydrargyrum, means "liquid silver." Many of these names are already familiar to you - gold, silver, copper, chlorine, platinum, carbon, oxygen, and nitrogen. The world new elements may be announced at any time.Įach element has a name. The search for new elements continues in many laboratories around Time, elements 107 and 109 have been identified among the products of a nuclear By 1980, 106 of these had been unequivocally characterized and acceptedīy the International Union of Pure and Applied Chemistry (IUPAC). The atoms of each element are chemically distinctĪnd different from those of any other element. ![]()
