Periodic Table of Elements 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 " Chemical Elements Sorted By " section with links that will sort chemical elements by various properties. What's New Don't like banner ads? Well neither do we, but they are the most effective method for us to generate the revenues necessary to operate this site while making our content available free of charge. Now, however, we have an option that will reward those who directly support our efforts with the ability to access this site banner ad free. SUBSCRIBE TODAY Many elements now include a page of common chemicals and chemical formulas that contain the given element. These chemical compounds in turn are linked to a page that contains more information on the chemical compound. As the underlying chemical database is a work in process, some chemicals will have very detailed information while others will have only basic information. If you know of resources (including public domain databases, or financial grants that would allow us to license databases); or are responsible for a database of chemical compounds and would like to partner with EnvironmentalChemistry.com; please contact us. Of particular short term interest to us is a table of data that cross references chemical formulas to CAS Numbers and/or chemical names.

6. THE CHEMICAL ELEMENTS An introduction to elements and element characterization. http://www.tryagain.com/chemistry/elements.htm

Metals Non Metals The Noble-Gas Elements Metalloids THE CHEMICAL ELEMENTS The 100 plus elements are the "alphabet" of matter because every tangible material is a combinations of these elements. The elements are categorized as: Metals Non-Metals Metalloids Noble Gases This main categorization is based on the electrical attributes of the elements. Some elements tend to "lose" an electron, and become postively charged. (These are the metals), Other elements tend to "acquire" an electron, and become negatively charged, (the non metals). The third group, (metalloids), fall in between these two extremes. And the Noble Gas category is "unelectrical" displays no interest in either acquiring and losing an electron, but unlike the metalloids who can be "persuaded" one way or the other the noble ones simply don't engage. By far, most elements in the periodic table are metals (about three quarters). There are eight semi-metals (metalloids), six noble gases, and 12 non-metals. The current theory of the creation of the universe suggests that in the beginning there was only hydrogen the smallest atom, and then it fused into the larger atoms. Still today hydrogen is the most abundant atom in the universe (90% in count, 75% in weight).

var cm_role = "live" var cm_host = "angelfire.lycos.com" var cm_taxid = "/memberembedded" The Perfect Guide to Chemistry Atom Structure Electron- The electron is a negatively charged subatomic particle and is found outside of the nucleus. Proton- The proton is a subatomic particle that is positively charge and is found in the nucleus of the atom. Neutron- The neutron is the subatomic particle that is neutral in charges, doesn't have an electric charge and is also found in the nucleus of an atom. Nucleus- The nucleus of the atom is consisted of the protons and neutrons and are located right in the center of the atom where both, protons and electrons are stuck together. Periodic Table Introduction What does the periodic table show? ? ? The periodic table is a chart, created by famous Russian scientist Dmitri Mendeleev. It shows all the elements that excist such as oxygen,It has specific facts about each of them such as the ones listed below : Atomic Number Mass Number Number of Protons in Atom Number of Electrons in Atom Chemical Symbol Number of Neutrons in Atom Metal / Nonmetal Chemical Activity Oxidation Number Electron Energy Levels Electron Energy Sublevels Orbitals within Sublevels Electron Configuration Families of Elements Natural / Manmade Physical State at Room Temperature Basic Structure The periodic table sometimes shows whether it is artificially made or whether it is radioactive or not. It is divided in metallic or non-metallic gases. It is also divided into other groups like halogen gas, noble gases, alkali metals and alkaline-earth elements. These groups go under the transition metals and most active metals. Periods in a periodic table are horizontal rows and are numbered from 1 to 7. Also, in a periodic table, elements with similar properties are put under each other in the vertical columns or groups. The following are a description of each of the 4 groups:
