Answer correctly to win. Cellulose, a primary component, has a chemical formula, (C6H10O5)n, but paper is too much of a mixture to have a single chemical formula. It’s chemical formula is NaCl, Please give me the electronic structure of first 20 elements. The element names and symbols may be proposed by the element discoverer, but often undergo revision before final approval. That’s the case with tungsten. [12], The following is a list of isotopes of elements given in the previous tables which have been designated unique symbols. The corresponding standard atomic weights are: This element sublimes at one atmosphere of pressure. The atomic weight of commercial lithium can vary between 6.939 and 6.996—analysis of the specific material is necessary to find a more accurate value. For more detailed information about the origins of element names, see List of chemical element name etymologies. Also given is each element's atomic number, atomic weight, or the atomic mass of the most stable isotope, group and period numbers on the periodic table, and etymology of the symbol. Many of these symbols were designated during the early years of radiochemistry, and several isotopes (namely those in the decay chains of actinium, radium, and thorium) bear placeholder names using the early naming system devised by Ernest Rutherford.[14]. Since 2009, IUPAC provides the standard atomic-weight values for these elements using the interval notation. [209], indicates the mass number of the longest-lived isotope of the element. There are also some historical symbols that are no longer officially used. Chemical symbols are abbreviations used in chemistry for chemical elements, functional groups and chemical compounds. A sample consisting the atoms of a single element, weights the sample in grams and separates the element … This is a list of elements by atomic number with symbol. A few such examples have been listed below. "The Periodic Table, Its Story and Its Significance". However, Latin symbols are also used, especially in formulas. Calculated from the atomic weight and the atomic volume. The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. Atomicity is defined as the total number of atoms that constitute a molecule. These elements include some of the most abundant in the universe (hydrogen, oxygen, carbon) as well as some of the most unusual (phosphorus, boron). Your email address will not be published.

For example, d6-benzene and C6D6 can be used instead of [2H6]C6H6. Attached subscripts or superscripts specifying a nuclide or molecule have the following meanings and positions: In Chinese, each chemical element has a dedicated character, usually created for the purpose (see Chemical elements in East Asian languages).
