Using the difference of ionic electronegativity expressed/designated as XA and XB. The formula is written as %IC={1-exp[(-0.25)(XA-XB)^2]}*100. the procedure is put in your electronegativities, (the order doesn't matter because we square the difference) and then square the difference. Then multiply that by -0.25 and put it on the exp, which you then subtract from one and times by 100. The exp is the way they write e^x for some reason.
Example: %IC of TiO2
electronegativity:
Ti=1.5
O=3.5
%IC={1-e^[(-0.25)(1.5-3.5)^2]}*100
1.5-3.5=-2
%IC={1-e^[(-0.25)(-2)^2]}*100
-2^2=4
%IC={1-e^[(-0.25)4]}*100
-0.25*4=-1
%IC={1-e^-1}*100
e^-1=0.367879441
%IC={1- 0.367879441 }*100
1- 0.367879441=0.632120559
%IC=0.632120559*100
0.632120559*100=63.2120559
Do your rounding, add a % sign and %IC of TiO2= 63%
The way I find percentages is: To find 17% I: Find 10 percent, Then half the 10 percent, to get 5 percent which makes 15%. Then find a 5th of the 5 % and double it to make 17%
find 10% * it by 2 find 1 percent * it by 2 add together
8% of 50 = 4
if you received 85.0 percent back from your product then your percent yield is 85 percent.

The BrF bond has 30 percent iconic character.
Ionic
% ionic character= (1-exp(-(0.25)(XA-XB)2))x100
I
The bond between oxygen and fluorine shows polar covalent character.
To find percentage ionic character, use the formula: % ionic character = {1- exp[-(0.25)(Xa - Xb)2]} x 100 Where Xa and Xb are the electronegativities for the respective elements. This is according to the science textbook, "Fundamentals of Materials Science and Engineering: An integrated approach" by William D Callister.

Barium Oxide = BaO Electronegativity (Pauling's) Ba = 0.89 O = 3.44 |0.89-3.44| = 2.55 Difference in electronegativity = 2.55 Percent Ionic Character ~ 79%
The ionic character of NO3 is -1.
what is a ionic character what is a ionic character what is a ionic character
Covalent bonds have ionic "character" when they are polar. The more polar, (greater the electronegativity difference) the more ionic character.
Cu-Cl is more ionic than I-Cl as the difference in the electronegativity is more in the case of Cu and Cl.
