Question

Silicon is the fundamental component of integrated circuits. Si has the same structure as diamond.Is Si a molecular, metallic, ionic, or covalent-network solid?

Jules Bruno · Accepted Answer

We’re being asked to determine if Si is molecular, metallic, ionic or covalent-network solid.There are two main categories which are crystalline and amorphous solids. Crystalline solids are well ordered at the atomic level and amorphous solids are disordered. There are four types of crystalline solids:Ionic crystals – The ionic crystal structure consists of alternating positively-charged cations and negatively-charged anions. The ions may be monoatomic or polyatomic.Metallic crystal - Metallic crystals consist of metal cations surrounded by a "sea" of mobile valence electrons. These electrons, also referred to as delocalized electrons, do not belong to any one atom, but are capable of moving through the entire crystal.[readmore]Covalent network crystals - A covalent network crystal consists of atoms at the lattice points of the crystal, with each atom being covalently bonded to its nearest neighbor atoms. The covalently bonded network is three-dimensional and contains a very large number of atoms.Molecular crystals - Molecular crystals typically consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces. The intermolecular forces may be dispersion forces in the case of nonpolar crystals or dipole-dipole forces in the case of polar crystals.Given: Silicon is the fundamental component of integrated circuits. Si has the same structure as diamond.Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure. It is a network covalent solid with no molecular boundaries.Since diamond is a network covalent solid, Si is a network covalent solid or covalent-network solid.Si is a covalent-network solid.
