Chemistry Worksheet-Polarity of Bonds 1. Determine the type of bond (ionic, polar covalent, or non-polar covalent) that will form between atoms of the following elements and show the polarity of the bond if it is polar covalent. a. Ca and Cl TONG 30-10-20 b. C and S 25-25-0 c. Mg and FOMIC 4.0-12-38 d. N and O 35-30-05 c. Hand O Polar f. Sand O polar 35-2.5-10 II. The bonds between the following pairs of elements are covalent. Arrange them according to polarity, naming the most polar bond first on the side of the sheet a.H-C1 302109 b. H-C25-21-04 24 H-0 35-2.1-1-4 (6) H-H21ないも 4.SC 50 25-05 III. Using the table of electronegativities from your Periodic table, calculate the HN difference for the atoms that are bonded in the following molecules. Then tell whether the bond is nonpolar covalent, polar covalent, or ionic. Tell which atom has the greater share of the bonding electrons. In your drawing, show which atom is partially positive or partially negative if it is a polar covalent bond.
