Answer 2

The difference is about 1.0 which I estimate is about 25% ionic character. Actually you don't need a graph to make an estimate. You know approx 1.8 or 1.9 difference is about 50%. 0 difference is 0% ionic which makes 1.0 about 25% and 0.5 about 10% or so.

Answer 3

I checked and it's actually not 25%

Answer 4

Note I said ABOUT 25%. I did look at the graph your post provided. IF you want to try to draw a straight line through all of those points, which actually can't be done, then try and mark off tenths between 1.0 and 2.0, you may come up with 30% or 20% or anything in between. Frankly, trying to get more than that out of the so-called graph is a losing cause. Trying to eyeball that graph and reading between 23% and 25% (or whatever and 25%) is not worth the trouble in my opinion.

Answer 5

Thank you, i found out it's 30%, this question is really a trial and error.
