magnesium and also flourineMetals and nonmetals have tendency to kind ionic bonds.
You are watching: Which pair of elements is most likely to form an ionic bond?
Nonmetals and nonmetals tend to kind covalent bonds. Mg is a metal and F is a nonmetal. N and S are both nonmetals. O and also Cl room both nonmetals. Na and also Al space both metals.
upper rightYes. Covalent compounds are formed from aspects with small differences in electronegativity, or nonmetal elements. This are uncovered in the upper right edge of the regular table.
Which the the following has only covalent bonding and no ionic bonding?*NaOH *Na2SO4*CCl4*Ca(NO3)2
CCl4Yes. In Na2SO4, Ca(NO3)2, and NaOH a polyatomic ion is coupled v a steel cation. When covalent bonds affix atoms in ~ the polyatomic ion, ionic bonds attach these polyatomic ions to the steel cations. Only CCl4, which contains 4 C-Cl bonds (which indicate bonding between two nonmetallic elements), has covalent bonds and also no ionic bonds.
polar, v the chlorine end having a partial negative charge.Yes. As chlorine is more electronegative 보다 phosphorous, the chlorine end of the shortcut will have actually a partial negative charge. A P-Cl bond would be polar.

Which link is many polar? girlfriend will need to look up a table that electronegative to answer this question. Cl‒ClI‒ClP‒ClP‒I
P‒ClYes. Phosphorous and also chlorine have the greatest difference in electronegativities. Therefore, the P-Cl shortcut is the many polar.
