15. 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).

Natural potassium is composed of three isotopes, including potassium-40 (0.0118%), a radioactive isotope with a half life of 1.28 x 10 years. Properties Uses Potash is in high demand as a fertilizer. Potassium, found in most soils, is an element that is essential for plant growth. An alloy of potassium and sodium is used as a heat transfer medium. Potassium salts have many commercial uses. Sources Potassium is the 7th most abundant element on earth, making up 2.4% of the earth's crust, by weight. Potassium is not found free in nature. Potassium was the first metal isolated by electrolysis (Davy, 1807, from caustic potash KOH). Thermal methods (reduction of potassium compounds with C, Si, Na, CaC

Next 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:
