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

Apr 30, 2017

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.
