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 January 27 (while element 118 has been synthesized

The Origin of the Periodic Table I know what the periodic table looks like, but where did it come from? Whose idea was it to arrange the elements this way? In 1869, a Russian chemist named Dmitri Mendeleev came up with a way of organizing the elements that were known at the time. He set them out in order of atomic weight , and then grouped them into rows and columns based on their chemical and physical properties. 1869...that's way before the , or even the Rutherford model That's right. Mendeleev had no idea what atoms were made of or why they behaved as they did. Nevertheless, he was able to put together the periodic table almost as we know it todayexcept that some elements were missing, because they were unknown in 1869. Based on the gaps in his table, Mendeleev even succeeded in predicting the existence and properties of several new elements. That's pretty impressive. Can you tell me more about how Mendeleev organized the table? What kinds of properties did he use? His basic rule was this: the elements in any column, or

8. The Periodic Table Brief History. Dmitri Ivancritch Mendeléeff came up with the first version of the periodic table in 1864. Since then more than 700 versions of the table http://www.chem.lsu.edu/lucid/tutorials/Periodic_Table.html

The Periodic Table Brief History The periodic table is divided into three main sections: the metals, the nonmetals, and the metalloids. Each one of these groups contains elements with similar physical properties. Metals Metals makeup more than 75% of the elements in the periodic table. Metals are characterized by the following physical properties. 1. They have metallic shine or luster. 2. They are usually solids at room temperature. 3. They are malleable. Malleable means that metals can be hammered, pounded, or pressed into different shapes without breaking. 4. They are ductile meaning that they can be drawn into thin sheets or wires without breaking. 5. They are good conductors of heat and electricity. Nonmetals There are 17 nonmetals in the periodic table, and they are characterized by four major physical properties. 1. They rarely have metallic luster. 2. They are usually gases at room temperature. 3. Nonmetallic solids are neither malleable nor ductile. 4. They are poor conductors of heat and electricity. Metalloids The six metalloids are B, Si, Ge, As, Sb, and Te. The properties of the metalloids have characteristics in between that of the metals and the nonmetals. They are good conductors of heat and electricity, but they are not good conductors or insulators.
