How wold you rank these bonds from most ionic to most covalent in character? #Br-F#, #Ca-F#, #K-F#, #F-F#, #Cl-F#?

K-F, Ca-F, Br-F, Cl-F, F-F.
Explanation:
In order to find how ionic a bond is, you need to look at the differences in their electronegativity.
-
K-F would be the most ionic because K has an electronegativity of 0.82 and F has an electronegativity of 3.98
-
Ca-F would be next. Ca has an electronegativity of 1.00
-
Br-F. Br has an electronegativity of 2.96.
-
Cl-F. Cl has an electronegativity of 3.16.
-
F-F is the most covalent because the electronegativity values are the same so the difference would be zero.
