polymerization to promote the role of aluminum Keywords ranking
polymerization of aluminum, also known as chemical elements, refers to more than one hundred kinds of basic metals and non-metallic material in nature, they are only formed by an atom, each nucleus has the same number of protons in its atomic, chemical methods can not decomposition, and can constitute all the material. Some examples of common elements hydrogen, nitrogen and carbon. Until 2007, a total of 118 kinds of elements are found, of which 94 species exist on Earth. 1923, the International Atomic Weight Committee decision: the chemical elements according to how much of the nucleus charge of atom classification of a way to the same class of the nuclear charge number of atoms called an element.
