"Symbol (chemistry) In relation to the chemical elements, a symbol is a code for a chemical element. Many functional groups have their own chemical symbol, e.g. Ph for the phenyl group, and Me for the methyl group. Chemical symbols for elements normally consist of one or two letters from the Latin alphabet, but can contain three when the element has a systematic temporary name (as of March 2017, no discovered elements have such a name), and are written with the first letter capitalized. Earlier chemical element symbols stem from classical Latin and Greek vocabulary. For some elements, this is because"
"of naming and symbol conventions used by chemists until that time, he proposed to indicate each chemical element by a symbol of one or two letters, the first one being capitalized. The capitalization allowed formulae like ""NaCl"" to be written without spaces and still be parsed without ambiguity. Berzelius' system continues to be used, augmented with three-letter symbols such as ""Uue"" for unconfirmed or unknown elements and abbreviations for some common substituents (especially in the field of organic chemistry, for instance ""Et"" for ""ethyl-""). This has been further extended to describe the amino acid sequences of proteins and other similar"

The list given in ISO 31-8:1992 was quoted from the 1998 IUPAC ""Green Book"" Quantities, Units and Symbols in Physical Chemistry and adds in some cases in parentheses the Latin name for information, where the standard symbol has no relation to the English name of the element. Since the 1992 edition of the standard was published, some elements with atomic number above 103 have been discovered and renamed. Symbols for chemical elements shall be written in roman (upright) type. The symbol is not followed by a full-stop. Examples: Attached subscripts or superscripts specifying a nucleotide"

"Hill system order is arranged alphabetically, as above, with single-letter elements coming before two-letter symbols when the symbols begin with the same letter (so ""B"" comes before ""Be"", which comes before ""Br""). The following example formulae are written using the Hill system, and listed in Hill order: Chemical formula The connectivity of a molecule often has a strong influence on its physical and chemical properties and behavior. Two molecules composed of the same numbers of the same types of atoms (i.e. a pair of isomers) might have completely different chemical and/or physical properties if the atoms are connected differently or"
"These are often a single capital letter, and the letters are reserved and not used for names of specific elements. For example, an ""X"" indicates a variable group (usually a halogen) in a class of compounds, while ""R"" is a radical, meaning a compound structure such as a hydrocarbon chain. The letter ""Q"" is reserved for ""heat"" in a chemical reaction. ""Y"" is also often used as a general chemical symbol, although it is also the symbol of yttrium. ""Z"" is also frequently used as a general variable group. ""E"" is used in organic chemistry to denote an electron-withdrawing group"
"of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin ""natrium"". The same applies to ""W"" (wolfram) for tungsten, ""Fe"" (ferrum) for iron, ""Hg"" (hydrargyrum) for mercury, ""Sn"" (stannum) for tin, ""K"" (kalium) for potassium, ""Au"" (aurum) for gold, ""Ag"" (argentum) for silver, ""Pb"" (plumbum) for lead, ""Cu"" (cuprum) for copper, and"

Then, prefixes are used to indicate the numbers of each atom present: these prefixes are ""mono-"" (one), ""di-"" (two), ""tri-"" (three), ""tetra-"" (four), ""penta-"" (five), ""hexa-"" (six), ""hepta-"" (seven), ""octa-"" (eight), ""nona-"" (nine), and ""deca-"" (ten). The prefix ""mono-"" is never used with the first element. Thus, NCl is called nitrogen trichloride, PO is called diphosphorus pentoxide (the ""a"" of the ""penta-"" prefix is dropped before the vowel for easier pronunciation), and BF is called boron trifluoride. Carbon dioxide is written CO; sulfur tetrafluoride"

All other types of atomic nuclei are composed of two or more protons and various numbers of neutrons. The most common nuclide of the common chemical element lead, Pb, has 82 protons and 126 neutrons, for example. The table of nuclides comprises all the known nuclides. Even though it is not a chemical element, the neutron is included in this table. The free neutron has"

For example, Germans in the past have used ""J"" (for the alternate name Jod) for iodine, but now use ""I"" and ""Iod"". The first letter of a chemical symbol is always capitalized, as in the preceding examples, and the subsequent letters, if any, are always lower case (small letters). Thus, the symbols for californium and einsteinium are Cf and Es. There are also symbols in chemical equations for groups of chemical elements, for example in comparative formulas."

Since 2002, the IUPAC Inorganic Chemistry Division has been the official body responsible with assigning official names to new elements, with the IUPAC Council making the final decision. Once an element has been named, a one-, or two-letter symbol must be ascribed to it so it can be easily referred to in such contexts as the periodic table. The first letter is always capitalised. While the symbol is often a contraction of the element's name, it may sometimes"
"Pearson symbol The Pearson symbol, or Pearson notation, is used in crystallography as a means of describing a crystal structure, and was originated by W.B. Pearson. The symbol is made up of two letters followed by a number. For example: The two (italicised) letters specify the Bravais lattice. The lower case letter specifies the crystal family, and the upper case letter the centring type. The number at the end of the Pearson symbol gives the number of the atoms in the conventional unit cell. IUPAC (2005) The letters A, B and C were formerly used instead of S. When the"

It belongs to group 14 of the periodic table. Three isotopes occur naturally, C and C being stable, while C is a radionuclide, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Carbon's abundance, its unique"

"of C is −1 + − = −. The −1 occurs because each carbon is bonded to one hydrogen atom (a less electronegative element), and the − because the total ionic charge of −1 is divided among five equivalent carbons. Again this can be described as a resonance hybrid of five equivalent structures, each having four carbons with oxidation state −1 and one with −2. The oxidation state in compound naming is placed either as a right superscript to the element symbol in a chemical formula, such as Fe, or in parentheses after the name of the element in chemical"
"Chemical element A chemical element is a species of atoms having the same number of protons in their atomic nuclei (that is, the same atomic number, or ""Z""). For example, the atomic number of oxygen is 8, so the element oxygen consists of all atoms which have exactly 8 protons. 118 elements have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radionuclides, which decay over time into other elements. Iron is the most abundant"

His chemical table contains nine elements, namely lead, tin, iron, gold, copper, quicksilver, sulfur, and arsenic (but he listed sulfur and arsenic under minerals or chemical compounds). He assigned chemical symbols to the seven metals corresponding to the known celestial bodies at the time, Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon respectively.
