Types of Bonds y Covalent – a sharing of electrons between two nuclei; non-metal with non-metal y Ionic – transfer of electrons between two atoms; metal with non-metal
Background image of page 2
Ionic vs Covalent Bonds y Ionic Bonds – { Achieve e - configuration of noble gas by gaining or losing electrons { Metal with non-metal { Non-volatile (do not vaporize easily) { Ionize in polar solvents { Dissolve in polar solvents y Covalent Bonds – { Share e - ’s to achieve noble gas configuration { Non-metal with non-metal { Often volatile (vaporize easily) { Usually non-electrolytes, weak electrolytes at best
