WebApr 22, 2024 · Conductance is the measure of how easily electrical current (i.e. flow of charge) can pass through a material. Conductance is the inverse (or reciprocal) of electrical resistance, represented as 1/R. To have a better understanding of conductance, one must recall the resistance of an object. WebNov 16, 2024 · Ionic crystals are hard and brittle and have high melting points. Ionic compounds do not conduct electricity as solids, but do conduct electricity when molten or in aqueous solution. Figure 12.7. 1: NaCl crystal. Metallic crystal - Metallic crystals consist of metal cations surrounded by a "sea" of mobile valence electrons (see figure below).
