In many compounds, atoms will share electrons to enable their valence shell to become like the nearest Noble Gas. This is normally 8 electrons (the “Octet Rule”), apart from Hydrogen. There are exceptions (see next section). 05.02 Ionic/Covalent Bond Worksheet Valence electrons

Chemical Bonding Ionic Bond between a Metal and Non-Metal (M + NM) Covalent Bond between a Non-Metal and Non-Metal (NM + NM) Metallic Bond between a Metal and Metal (M+ M) Determine if the elements in the following compounds are metals or non-metals. Describe the type of bonding that occurs in the compound. Compound Element 1 (metal or non-metal?) Element 2 (metal or non-metal?) Bond Type NO 2 N = non-metal O = non-metal covalent NaCl Na= metal Cl=non metal Ionic SO 2 S = non metal O = non metal Covalent PO 4 3- P=non metal O=non metal Covalent MgBr 2 Mg=metal Br=non metal Ionic CaO Ca=metal O = non metal Ionic H 2 O H=non metal O = non metal Covalent K 2 O K=metal O = non metal Ionic Cu-Zn alloy Cu= metal Zn=metal Metallic O 2 O = non metal O = non metal Covalent CuCl 2 Cu= metal Ci=non metal Ionic NO 2 - N = non-metal O = non metal Covalent TiO 2 Ti=metal O = non metal Ionic HF H=non metal F =non metal Covalent Rb 2 S Rb=metal S = non metal Ionic Au-Ag mixture Au=metal Ag=metal Metallic Fe 2 O 3 Fe=metal O = non metal Ionic C 6 H 12 O 22 C=non metal H = non metal Covalent
