Electrons around the nucleus at a very high speed (\uf0b1 2200 km \/ sec.).<\/span> In the circular movement, although not much heavy electrons, so here should serve a relatively large centrifugal force, working and trying to release electrons out of its path.<\/span> Now the force is holding electrons circling the nucleus remains in its path?<\/span> Workers who hold the earth remains on the trajectory is gravity.<\/span><\/p>\n Gravity between electrons and atomic nuclei have not been sufficient, as is evident in the calculations, and can not hold electrons farthest to remain on its trajectory.<\/span> Therefore here should serve some other power, namely electricity.<\/span><\/p>\n Between the nucleus and the electrons are electric power.<\/u><\/strong><\/span><\/p>\n This kind of power is simple to prove.<\/span> We rub ruler mica (synthetic material \/ plastic) with a woolen cloth, so in this material to work a tensile force to the paper, which in principle is greater than the force of gravity.<\/span><\/p>\n Who is responsible for the electricity we call electric charge.<\/u><\/strong><\/span><\/p>\n Against the atomic nuclei, electrons are running an electric power.<\/span> So electrons have electric charge.<\/span> We say an electron as a charge carrier.<\/span> Because the nucleus also has the properties of electricity running, then the atomic nucleus also has an electric charge.<\/span> It is evident that the electrons are not mutual attraction, but repelling.<\/span> Similarly, the behavior of atomic nuclei (Figure 1.6).<\/span> Therefore, the electrons repel each other, atomic nuclei and electrons of mutual attraction, the nuclei must be different from the electron charge, meaning bring a different kind of charge to the charge of an electron.<\/span> Atomic nuclear charge is called a positive charge and the charge of an electron is called negative charge.<\/span> Thereby to apply electrical charges:<\/span><\/p>\n
