Classify the bonds formed between each pair s ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's pasition on the periadic table Do not conduct calculations Drag the appropriate items to their respective bins. ãHints To use electronegativity or metal versus nonmetal classifications to distinguish covalent, polar covalent, and ionic bonds When two bondod atoms attract electrons with equal strength, thec resull is a nonpolar covalet bond. A polacovalel bond is one in which the electrons are unequally shared between the atoms. An ionic hond resuits when the sharing is so unequal that fully charged ions form Eleclronegaivily difference an be used lo predict bond type. If electronegativities differ by more than 2 units, the bond is substantially ionic; if they difter by less than 2 units, the hond is polar covalent; and if the valucs arc cqual, the bond is nonpolar covalent. If you are ol given electronegativity values, you cari still predict the bond type using the perodic tabla. Metals havelow electronegativity compared to nonmetals So in general, we can predict that any metal- nonmctal combinaticn wil bc ionic and any nonmctal nonmetal combination wil be covalent. Iãelectronegativity values aren't given. you should assume that a covalent bond is polar unless it is behveen two atcoms of the same element Reset Help s and Br Cs and Cl Bãand Br Ba and O O and Br P and i Mg and N P and F onic Polar covalent Submit My Answers Give Up Part B
