These valence electrons are responsible for all chemical bonds between atoms. The solid form of silicon does not react with oxygen, water and most acids. For silicon (four valence electrons) the highest populated energy band, called the valence band, is full and so those electrons cannot gain energy and stay within the band - they cannot contribute to the electrical conduction process. Insulators. Electron Configuration Step-1: First, find the atomic number of potassium from periodic table. Now find carbon in the Periodic Table.Remember that it's symbol is 'C'.See it in the 4th Column. By directly showing the two-step transition from the semiconducting through the semimetallic to the metallic state in the valence electrons, we pinpoint the raised questions about the nature of the transient state in silicon.

In chemistry, valence, also known as valency or valency number, is a measure that gives the maximum number of chemical bonds that can be formed by an atom of a given element. The reader should note that as electrons cannot be seen with any currently available technology, they certainly cannot be seen using visible light and thus do not have color. Instead, silicon bonds covalently (most frequently with oxygen SiO2, but also with carbon). In writing the electron configuration for Silicon the first two electrons will go in the 1s orbital. The figure below shows four atoms (dark) bonded to four others within the volume of the cell. Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.
