Electronic Structure of Solids

Electronic Structure of Solids

Electronic Structure of Solids. In any solid, the cohesive forces that hold the solid together are due to the the Coulombic attractions between the electrons and the nuclei They are manifested in different types of solids as: Chemical Bonds Ionic Metallic Covalent Network
