(1)Primary Bonding- (a)IONIC BONDING Between metallic(M)and non metallic (X)elements: Metals gives up an electron to non metallic element M+and X ions are formed A Coulombic attraction is created The bonding is non-directional Mostly "diffused"among ceramic materials Typical example: Sodium chloride Na"(1) Primary Bonding- (a)IONIC BONDING Between metallic(M) and non metallic (X) elements: Metals gives up an electron to non metallic element M+ and X￾ions are formed A Coulombic attraction is created The bonding is non-directional Mostly “diffused” among ceramic materials Typical example: Sodium chloride
