and have little tendency to share electrons with other atoms. An element close to anoble gasin the periodic system, on the other hand, is reactive chemically because of the possibility of assuming the stable electronic configuration of the noble gas, by losing one or more electrons to another...
Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
Tennessine(symbol Ts), for element 117 Oganesson(symbol Og), for element 118 This followed a 5-month period of public review after which the names earlier proposed by the discoverers were approved by IUPAC. You can buy thisperiodic table posterand more at theWebElements periodic table shop. ...
1 Alkali and Alkalinse earth metals 2 Transition Metals More so than any of the other major groups of elements in the periodic table, the transition metals have shaped human history and have been the workhorses of industry. The disc...
Atomic mass:The standard atomic weight of an element is the average mass of the element written in atomic mass units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the...

This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by vario...
An extensive periodic table of elements with a lot of additional functions. In addition to the countless element properties it displays the danger symbols to every element. The perfect companion for school or professional life.
Only elements go onto the periodic table, andsteel is an alloy, not an element.Steelis made from multiple elements. Its basic formula includesiron(Fe) with trace amounts of carbon (C). Different types of steel made add other elements to enhance properties. For example, chromium (Cr) may ...
