Which pair of facets is most likely to form an ionic compound?*sodium and aluminum*oxygen and chlorine *nitrogen and sulfur*magnesium and also fluorine
magnesium and flourine
Metals and nonmetals tend to form ionic bonds.

You are watching: Which pair of elements will form an ionic bond?

Nonmetals and nonmetals often tend to type covalent bonds. Mg is a metal and also F is a nonmetal. N and also S are both nonmetals. O and also Cl room both nonmetals. Na and Al are both metals.
upper rightYes. Covalent compounds are formed from elements with little differences in electronegativity, or nonmetal elements. These are discovered in the top right edge of the routine table.
Which of the following includes only covalent bonding and also no ionic bonding?*NaOH *Na2SO4*CCl4*Ca(NO3)2
CCl4Yes. In Na2SO4, Ca(NO3)2, and NaOH a polyatomic ion is coupled through a metal cation. If covalent bonds affix atoms within the polyatomic ion, ionic bonds connect these polyatomic ion to the metal cations. Only CCl4, which includes 4 C-Cl binding (which indicate bonding in between two nonmetallic elements), has covalent bonds and no ionic bonds.
polar, with the chlorine finish having a partial negative charge.Yes. As chlorine is much more electronegative 보다 phosphorous, the chlorine finish of the bond will have a partial an adverse charge. A P-Cl bond would certainly be polar.

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