When you find another ion with which you can bond, write in the symbol and the charge. Then write the new compound formed by combining the two. Give the compound's name. -Remember: Only positive ions can bond with negative ions and vice versa!!! -Each compound on your sheet must be different. Cation Anion Compound Name

Show how these elements combine into octet-rule ionic compounds, as in the first example. First, draw atomic Lewis structures for the atoms and their O.R. ions. Show their charges, and use them to find the unit formula, and the name. Then draw atomic Lewis structures for all atoms in the formula unit together, show with arrows how all e s are transferred to make the ions, and draw the Lewis structure of the ionic compound. Unit formula Atoms O.R. ions Name Transfer e s with arrows Lewis Structure LizN le 1e 30 Lithium Li. + •N• Li. •N• Li. Li 30 Li Li Li :N: nitride )le Li. Pb and K and H

How do I determine if a compound is polar or nonpolar based by looking at something such as lewis structure or name?

Show how these pairs of elements combine into octet-rule molecular compounds, as in the first example. First, draw their atomic Lewis structures, then use any number of these atoms to build an O.R. molecule, with multiple bonds if needed (you may not add a charge to make it O.R. as an ion!). Draw the O.R. Lewis structure, write its formula and chemical name. Atoms O.R. molecule Formula Name Carbon dioxide •¢. and ö. ö=c=ö CO2 H + Se I + S

For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. element #1 element #2 sodium carbon hydrogen fluorine bromine bromine element pair will form a molecular compound molecular compound chemical formula 0 0 name 0 П 0 Ś
