WebApr 1, 2024 · Diamond cubic silicon is widely used for electronic applications, integrated circuits, and photovoltaics, due to its high abundance, nontoxicity, and outstanding physicochemical properties. WebCrystal structure. Silicon crystallises in a giant covalent structure at standard conditions, specifically in a diamond cubic lattice (space group 227). It thus has a high melting point of 1414 °C, as a lot of energy is required to break the strong covalent bonds and melt the solid.

A silicon atom has fourteen electrons. In the ground state, they are arranged in the electron configuration [Ne]3s 3p . Of these, four are valence electrons, occupying the 3s orbital and two of the 3p orbitals.
