Metallic Lattice Structure - Metal atoms have a weak hold on their outer shell or valence electrons. This allows the electrons to move freely through the metal without being bound to one atom. Each metal atom becomes a positively charged ion. Opposite charges attract and this electrostatic force provides multidirectional bonding between the positive ions and the 'sea 'of loose electrons around them. Ionic Lattice Structure - this occurs when metallic elements bond with non-metallic elemen...
