Silicon is a chemical element with symbol Si and atomic number 14.
The 1s, 2s, 2p and 3s subshells are completely filled while the 3p subshell contains two electrons out of a possible six. It has a negative temperature coefficient of resistance, since the number of free charge carriers increases with temperature.The hippies are missing, but Matala magic still flows and the village has been spruced up - well done!We are very excited for having the opportunity to guide you in Matala Creta and in our hotel.The electrical resistance of single crystal silicon significantly changes under the application of mechanical stress due to the piezoresistive effect. Heavily boron-doped silicon is a type II superconductor with a transition temperature Tc of 0.4 K Silicon in its more common crystalline form was not prepared until 31 years later, by Deville. By electrolyzing a mixture of sodium chloride and aluminium chloride containing approximately 10% silicon, he was able to obtain a slightly impure allotrope of silicon in 1854. Later, more cost-effective methods have been developed to isolate several allotrope forms, the most recent being silicene.Because silicon is an important element in high-technology semiconductor devices, many places in the world bear its name.
