Why is HF much more covalent than KI despite having a greater electronegativity difference? [duplicate]
Generally, the percent of ionic character in a two-element compound correlates quite well with the difference in the electronegativities of the two elements making up the compound, as can be seen in ...

The impossibility of 100% ionic bond
Recently, I read the definition of oxidation state on Wikipedia. It read that a 100% ionic bond is impossible. So what does a 75% ionic and 25% covalent bond mean at all?

Why isn't water an ionic compound?
If two alkali metal atoms join with an oxygen atom, an ionic bond forms. Since hydrogen has the same number of valence electrons as alkali metals, why can't water be ionic?
This is what I'm thinking:

Is the bond in HF ionic while it is covalent in HCl?
Why would a hydrogen atom "donate" to fluorine in an ionic bond but not in $\ce{HCl}$? Why would $\ce{H}$ and chlorine share instead of $\ce{Cl}$ just stripping it away like $\ce{F}$ does?

Is beryllium difluoride covalent or ionic?
My textbook says that despite the large electronegativity difference $\ce{BeF2}$ is covalent since the beryllium ion will have too much charge density and it will attract the fluorine electron cloud ...

Is carbon–sodium bond mainly ionic or covalent?
We all know that carbon mostly forms covalent bonds (almost always) and sodium mostly forms ionic bonds (almost always). But if $\ce{NaOH}$ reacts with ethyne, then $\ce{HC#CNa}$ and $\ce{H2O}$ are ...

Covalent and Ionic bonds with Semi-metals
why are some semimetals considered as a metal, and some, a nonmetal when paired with some atoms.
Like in BF, it is an ionic bond, but in SiCl, it is a covalent bond.
Do their electronegativities ...
