Which pair of elements will form an ionic bond?
N and O
K and Br
C and Cl
Fe and Ni

Respuesta :

K and Br can form an ionic bond.  Since potassium is a metal (has a small electronegativity) and bromine is a nonmetal (has a large electronegativity), potassium can give an electron to bromine creating potassium bromide.

I hope this helps.  Let me know if anything is unclear.
