PERIODIC TABLE, CHEMICAL BONDING, CHEMICAL FORMULAS, NAMING OF CHEMICAL COMPOUNDS QUESTION 3 1. Using the periodic table, (i) classify each of the following elements as a metal or a nonmetal, and then (ii) for those elements identified as metals further classify each as a main-group (representative) element, transition metal, or inner transition metal: (a) europium (b) indium (c) lithium (d) oxygen (e) terbium (5) 2. For each of the following compounds, state whether it is ionic or covalent. If it is ionic, write the symbols for the ions involved: (a) NF3 (b) BaO (c) (NH4)2CO3 (d) Sr(H2PO4)2 (e) IBr (f) Na2O PERIODIC TABLE, CHEMICAL BONDING, CHEMICAL FORMULAS, NAMING OF CHEMICAL COMPOUNDS QUESTION 3 1.
