Room temperature, Silicon-elemental nature not lively. Silicon there is a clear non-metallic properties, and soluble in solutions of alkali metal hydroxides, (partial) silicate and hydrogen.
Silicon atoms in the IV group of the periodic table of the elements, and its atomic number is Z=14, the nucleus has 14 electrons. Electrons outside the nucleus, energy levels from low silicon atoms to high, from the inside out, layers of wrap, which is called the electronic shell structure. Orbital electron the first layer of silicon atoms 2 electrons, the second floor has 8 electrons to reach steady-state. Has 4 electrons the outermost valence electrons, conductivity of the silicon atom plays a leading role.
