ec- 6: ewis Theory Lec 26: Lewis Theory Roy A. Lacey, Stony Brook University; Che 131, Spring 2012 1 Chemical bonds result from the attractive interactions which holds atoms together in molecules and compounds. Atoms may transfer or share electrons, and either process may provide for a stable arrangement of electrons between the atoms that results in the formation of molecules. Ionic Bonds , Covalent Bonds , and Metallic Bonds. Roy A. Lacey, Stony Brook University; Che 131, Spring 2012 2 Bond types iBd ` Formed from electrostatic ttractions of closely packed, Ionic Bond attractions of closely packed, oppositely charged ions. ormed when an atom that ` Formed when an atom that easily loses electrons reacts with one that has a high lectron affinity electron affinity . ` When a nonmetal and a metal react ,the valence orbitals of the metal are emptied to achieve noble gas electron pg configuration. The valence orbitals of the nonmetal gains electrons to achieve a noble gas electron configuration. Roy A. Lacey, Stony Brook University; Che 131, Spring 2012 3 Bond types Covalent Bond ` When two nonmetals react : They share electrons to achieve Noble Gas Electron onfiguration. configuration. If the electrons are shared equally, a covalent bond is rmed formed. Roy A. Lacey, Stony Brook University; Che 131, Spring 2012 4

Favored electron configurations Noble gas electron configurations are favored Roy A. Lacey, Stony Brook University; Che 131, Spring 2012 5 Lewis Theory of Bonding ` Atoms form bonds by sharing electrons. Through the sharing process, each atom cquires enough electrons to mimic the electron acquires enough electrons to mimic the electron configuration of a noble gas.
