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

Answer 1

Henry Antrim

K-F, Ca-F, Br-F, Cl-F, F-F.

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.

Characteristically, K-F, Ca-F, Br-F, Cl-F, and F-F are the most ionic to the most covalent.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
