  Chemical element   (Site not responding. Last check: 2007-11-06)
For example, all atoms with 6 protons in their nuclei are atoms of the chemical element carbon, and all atoms with 92 protons in their nuclei are atoms of the element uranium.
Atoms of the same element whose nuclei contain a different number of neutrons are said to be different isotopes of the element.
The official names of the chemical elements are decided by the International Union of Pure and Applied Chemistry, which generally adopts the name chosen by the discoverer.

However, atoms of the same element may differ in the number of neutrons, and are known as isotopes of the element.
The atomic mass of an element, A, is measured in unified atomic mass units (u) and is roughly equal to the sum of the protons and neutrons in the nucleus of an atom of the element.
The naming of elements precedes the atomic theory of matter, although at the time it was not known which chemicals were elements and which compounds.

The names for the chemical elements 104 to 108 have been the subject of a major controversy starting in the 1960s which was only finally resolved in 1997.
At issue was the convention that elements are named by their discoverers which led to controversy when multiple groups claimed discovery simultaneously.
Element 104 was named after Igor Kurchatov who was father of the Russian atomic bomb, and this was one reason the name was objectionable to the Americans.

 Systematic name - Wikipedia, the free encyclopedia
Systematic names for chemical elements and chemical compounds (administered by the IUPAC)
Compounds with a positive ion (cation), the name of the compound is simply the cation's name (usually the same as the element's), followed by the anion.
An older, deprecated notation is to append -ous or -ic to the root of the Latin name to name ions with a lesser or greater charge.

 Systematic element name - Wikipedia, the free encyclopedia
The provisional names are derived systematically from the element's atomic number.
As of 2005, ununquadium, element 114, is the highest confirmed element known, with elements 115 (ununpentium), 116 (ununhexium) and 118 (ununoctium) awaiting confirmation.
There are 702 possible combinations of letters given single letter and double letter naming used in official element names, less than the 1000 possible names using the triple letter provisional naming scheme.

 Systematic element name
The IUPAC uses a systematic naming system for new chemical elements.
In the case of elements 104 and higher, this has been a protracted and highly political process (see element naming controversy).
Element 115 1(un) + 1(un) + 5(pent) + ium = Ununpentium.

Roentgenium (former temporary name: unununium or eka-gold) is a chemical element in the periodic table that has the symbol Rg (formerly temporarily Uuu) and atomic number 111 making it one of the super-heavy atoms.
It is a synthetic element whose longest-lived isotope has a mass of 280 and a half-life of 3.6 seconds.
The name roentgenium was accepted as a permanent name on November 1, 2004 in honour of Wilhelm Roentgen; before this date, the element was known under the temporary IUPAC systematic element name unununium.

Element 112 is one of the superheavy elements and its atoms decompose through the emission of alpha particles with a half life of only about 240 µs.
This element was created by fusing a zinc atom with a lead atom by accelerating zinc nuclei into a lead target in a heavy ion accelerator.
It is named Ununbium, as in 1-1-2-ium, a temporary IUPAC systematic element name.

The systematic name encodes the structure and composition of the caffiene molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" just names it.
Compounds with a positive ion (cation), the name of the compound is simply the kation's name (usually the same as the element's), followed by the anion.
The naming sceme for organic compounds is complex and still developing, as is knowledge of the compounds themselves.

The atomic mass of an element, A, is measured in unified atomic mass units (u) is the average mass of all the atoms of the element in an environment of interest (usually the earth's crust and atmosphere).
The 23 elements not found on earth are derived artificially; the first purportedly synthesized element was technetium, in 1937, although the trace amounts of naturally occurring technetium were not known then.

Oxygen is the chemical element in the periodic table that has the symbol O and atomic number 8.
The name "oxygen" was chosen because, at the time it was discovered in the late 18th century, it was believed that all acids contained oxygen.
It was named by Antoine Laurent Lavoisier in 1774.

 Element names >100
Elements of atomic numbers greater than 103 are often referred to in the scientific literature but receive names only after they have been 'discovered'.
The existence of a systematic nomenclature for the unknown elements does not deny the right of 'discoverers' of new elements to suggest other names to the Commission after their discovery has been established beyond all doubt in the general scientific community.
The systematic names and symbols for elements of atomic numbers greater than 103 are the only approved names and symbols for those elements until the approval of trivial names by IUPAC.

 Element naming controversy   (Site not responding. Last check: 2007-11-06)
The American name to 106 was objectionable to some because Glenn T. Seaborg was still alive and handing out autographed periodic tables and hence his name could not be used for an element in accordance with the IUPAC rules.
This was objected to by the American Chemical Society on the grounds that the right of the American group to propose the name for element 106 was not in question and that group should have the right to name the element whatever it wanted to.
Indeed, IUPAC decided that the credit for the discovery of element 106 should be shared between Berkeley and Dubna but the Dubna group had not come forward with a name.

 Dog Latin - Wikipedia, the free encyclopedia
One well-known use of dog Latin is in the temporary naming of undiscovered (or not yet officially named) chemical elements.
For example, the name given to element 118 is "ununoctium", the IUPAC systematic element name, from the Latin words for "one one eight".
The names of spells employed by JK Rowling in the Harry Potter books are a well-publicised example, such as 'Petrificus Totalus'.

Meitnerium is a chemical element in the periodic table that has the symbol Mt and atomic number 109.
It is a synthetic element whose most stable isotope is Mt-266 with a half-life of 3.4 ms.
The name meitnerium was suggested in honor of the Austrian-Swedish physicist and mathematician Lise Meitner, but there was an element naming controversy as to what the elements from 101 to 109 were to be called; thus IUPAC adopted unnilennium (symbol Une) as a temporary, systematic element name.

Ununoctium is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Uuo and has the atomic number 118.
The name Ununoctium is used as a placeholder, such as in scientific articles about the search for Element 118; it is Dog Latin "one-one-eight-ium" ("ium" being a standard ending for element names).
Such transuranic elements are always artificially produced, and usually end up being named for a scientist or the town of their discovery รก la darmstadtium.

There was an element naming controversy as to what the elements from 101 to 109 were to be called; thus IUPAC adopted unnilseptium (symbol Uns) as a temporary, systematic element name for this element.
While this conforms to the names of other elements honoring individuals, where only the surname is taken, it was opposed by many who were concerned that it could be confused with boron.
Despite this, the name bohrium for element 107 was recognized internationally in 1997.
