Which pair of elements is most most likely to kind an ionic compound?*sodium and aluminum*oxygen and also chlorine *nitrogen and sulfur*magnesium and also fluorine
magnesium and also flourine
Metals and nonmetals have tendency to kind ionic bonds.

You are watching: Which pairs of elements are likely to form ionic compounds

Nonmetals and nonmetals tend to form covalent bonds. Mg is a metal and also F is a nonmetal. N and also S are both nonmetals. O and Cl room both nonmetals. Na and also Al space both metals.
upper rightYes. Covalent compounds are developed from facets with small differences in electronegativity, or nonmetal elements. This are discovered in the upper right edge of the routine table.
Which that the following has only covalent bonding and no ionic bonding?*NaOH *Na2SO4*CCl4*Ca(NO3)2
CCl4Yes. In Na2SO4, Ca(NO3)2, and also NaOH a polyatomic ion is coupled v a steel cation. When covalent bonds affix atoms within the polyatomic ion, ionic bonds affix these polyatomic ion to the steel cations. Only CCl4, which contains 4 C-Cl bond (which show off bonding in between two nonmetallic elements), has covalent bonds and also no ionic bonds.
polar, through the chlorine finish having a partial negative charge.Yes. As chlorine is an ext electronegative 보다 phosphorous, the chlorine finish of the bond will have a partial an adverse charge. A P-Cl bond would be polar.

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