Chemieb¼cher (DE) The periodic table The periodic "law" of chemistry recognises that many properties of the chemical elements are periodic functions of their atomic number (the number of protons within the element's atomic nucleus). The periodic table is an arrangement of the chemical elements ordered by atomic number in columns ( groups ) and rows ( periods ) presented so as to emphasize their periodic properties. The element polonium is very much in the news at present, perhaps for the first time ever, and for the wrong reasons. This site does contain further information about polonium The groups (columns in the periodic table) are numbered 1-18. Some groups enjoy non-systematic names as well. The include Group 1 (alkali metals), Group 2 (alkaline earth metals), Group 15 (pnictogens, or pnicogens), Group 16 (chalcogens), Group 17 (halogens) and Group 18 (noble gases). While not groups in the periodic table, some other groupings of elements are often named as well. These include the lanthanoids (less preferably lanthanides) and actinoids (less preferably actinides). There are many different ways, sometimes ingenious, of arranging the chemical elements according to which properties are of particular interest but that shown here is a standard form of the periodic table. The relative merits of various other periodic table organisations is still the subject of debate. Particularly useful versions include the following:

These elements are found on earth in only very small amounts. Elements 90 to 103 are known as the actinide elements.

Periodic table From Wikipedia, the free encyclopedia Jump to: navigation search "The Periodic Table" redirects here. For the book by Primo Levi , see The Periodic Table (book) For a diagram of the periodic table, see standard periodic table below The periodic table of the chemical elements is a tabular method of displaying the chemical elements . Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior. The periodic table is now ubiquitous within the academic discipline of chemistry , providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior. The table has also found wide application in physics biology engineering , and industry . The current standard table contains 117 confirmed elements as of October 16 (while element 118 has been synthesized
