Elemental you'll mention patha imagine??? Many people may think of stone, clay minerals, but actually everything in the country. In the world, even in the universe, then there is the element of the element, or in the lives of people every day, we rely on the element of life, because the element is vital to sustain life is very simple. All around us, every day, you see. You may not know that it is an element of house building cars or even a pen, pencil, you catch the regularly every day, but it is an element. So we must study to learn about the element, which can be found from where??? Studies from the workplace, which is also the periodic table in the study of elements, it can be divided into three main topics, namely. 1. evolution of the periodic table of the elements by Treasure 2. periodic table of elements and benefits 3. periodic table. 1. the evolution of table furnicular 1817 Johannes Rietberg de aboe (Johann Dobereiner) mite is a chemist who first tried to organize into groups according to the element 3 element similar treasures. Called "three-packs" and found that the central element will have the atomic mass is the average of the remaining element, but when the master of the third element to another element that has a similar treasure will not be possible. Make sets of three digits of your banner, so it mite not aboe de as acceptable. Later in the year (1864), John Newlands (John Newlands) British chemists have found that, when the elements are sorted according to atomic mass, descending, horizontal row. The properties of the element will look similar, such as stalling, which occurs every elemental 8 retrieve Alabama rules of that law of octaves or walaen Newlands ' law of octaves, however, this rule is not recognized. After that, during the 1821 1269 – 1270 u lip Nevis Myers (Julius Meyer), a German scientist and Moraitis. Domain, Adelaide f. (Dimitri Mendelejev) scientist in Russia have found a comparable time that any properties of the element are associated with atomic mass of elements, that is, "If the sort of elemental according to atomic mass from ascending to discover that the treasure is there thatu similar stalling" which email de les.Ofdai rules rule set is called the "PHI" or rules of optional periodic table (Periodic law), so in honor of Adelaide f. domain called "table, a table of PC Digby's domain, Adelaide f." or periodic table of domain de Lake (periodic table Mendelejev ' s) but later Henry Morin (Henry Moseley.British scientists solved) periodic table of Adelaide includes the correct Acer motherboards by atomic number or number of protons that are found in the nucleus of the element. With relation to the atomic mass of elements rather than treasure. Made in accordance with the rules of optional PC rather than the periodic table can be created without the need to switch to the elements of some trace elements like incidents sorted by atomic mass. About the year (1913) proposed a new periodic table sali modules sorted by ascending atomic number and arrange elements similar properties, in the same periodic table new rules defined as "any properties of the elements in the periodic table, depending on the atomic numbers of the elements" to become a periodic table on the market today, so it can be seen that Johannes Rietberg de aboe how John Newlands Manor u lip Nevis Myers Moraitis. Domain f and Adelaide Henry sali modules cause the evolution of periodic table periodic table as in the present. 2. the properties of the element according to the periodic table. The first is the treasure of treasures, Atomic size and Atomic size trend. When considering the Atomic size will decrease from left to right, and when considering the. The size of the atom larger from top to bottom. The treasure is the treasure of the ionization energies. Ionization energy is the energy used to extract electrons from atoms in State 1, the gas particles become positive ions tend to consider the. The element in the same villages Ionization energy decreases from top to bottom. When considering the Inconsistency Ionization energy increases from left to right. The third treasure is a treasure of electrolyte Negara Carlo Villa hit refers to the ability to attract electrons in bonding to itself by considering the. The element that is in the same peninsula are valuable EN increase from left to right. When considering the Element in the same value decreases from top to bottom, EN, and the fourth is a treasure trove of treasure, boiling point and melting point by considering the. IA IIA IIIA and IVA Mu element melting point and the boiling point is likely even higher, especially villages, respectively, the IVA would have a melting point and the boiling point as high as possible. Part VIIA and VIIIA VA villages VIA the melting point and the boiling point is low. When considering the found that the melting and boiling points of the elements moo.9 IA IIA and IIIA majority is reduced when an atomic number increase or decrease likely from top to bottom by Moo. Elemental parts VIIA and VIIIA VA VIA villages have a melting point and boiling point increases with the atomic numbers for the melting and boiling points of the elements moo.9. IVA is likely not clear because the element IVA villages have structure and bond strength between different atoms, so the trend could not be concluded. Therefore, the arrangement of the periodic table, we notice. The properties of the element a little easier.
