Silicon is a hard, relatively inert metalloid and in crystalline form is very brittle with a marked metallic luster. Silicon occurs mainly in nature as the oxide and as silicates. The solid form of silicon does not react with oxygen, water and most acids. Silicon reacts with halogens or dilute alkalis.

Silicon crystallizes in a diamond cubic crystal structure by forming sp 3 hybrid orbitals. [48] A silicon atom has fourteen electrons. In the ground state, they are arranged in the electron configuration [Ne]3s 2 3p 2. Of these, four are valence electrons, occupying the 3s orbital and two of the 3p orbitals.
Shorthand electron configuration of Silicon: [Ne] 3s 2 3p 2 . Ionization Energies of Silicon. The following table lists the ionization energies IE (ionization potentials); the IE is the energy required in electron volt (eV) per atom to separate a given electron from an Silicon atom.
