Basic Concepts of Chemical Bonding 8.1 Chemical Bonds, Lewis Symbols, and the Octet Rule. In chemistry, we refer to Chemical bonding as a means or a way by which an atom attaches itself with other atoms. /Producer (pdfFactory Pro 3.50 \(Windows XP Professional Arabic\)) �-&�q#ڡ���R�C�4� ���@�~��y@ԍv7�L�u��(��X��r���). Chemical Bond - Attractive force between NUCLEI and VALENCE e- of different atom that binds them together. << The bond with the highest bond order is both the shortest and the strongest. In bonds with the same bond order between different atoms, trends are observed that, with few exceptions, result in the strongest single bonds being formed between the smallest atoms. 732 0 obj <> endobj When two elements engage in ionic bonding, one or more electrons are transferred from the metal to the nonmetal, forming ions (charged atoms). 8.2 Ionic Bonding • Consider the reaction between sodium and chlorine: Na(s) + ½ Cl.
