QuestionMost ionic $\square$ Most covalent Anumer Bant $\mathrm{Ca}-\mathrm{F}$ $\mathrm{Cl}-\mathrm{F}$ Br-F $\mathrm{K}-\mathrm{F}$ $\mathrm{F}-\mathrm{F}$

Studdy Solution
Rank the bonds from most ionic to most covalent: - Most ionic: $\mathrm{K}-\mathrm{F}$ (3.16) - $\mathrm{Ca}-\mathrm{F}$ (2.98) - $\mathrm{Br}-\mathrm{F}$ (1.02) - $\mathrm{Cl}-\mathrm{F}$ (0.82) - Most covalent: $\mathrm{F}-\mathrm{F}$ (0.00)
The bond with the most ionic character is $\mathrm{K}-\mathrm{F}$, and the bond with the most covalent character is $\mathrm{F}-\mathrm{F}$.
