how do i calculate the percentage of ionic character ..
ex. H-O = electronegativity difference = 1.2
Scroll down to problem 3 in the site below. The formula is there.

thnx for helping but the web site doesnt work
Try this. I tried to put it inside the sentence an that won't work. If this doesn't work I'll redo it from scratch.

OK. That one works.
thanks
To calculate the percentage of ionic character in a chemical bond, you can use the concept of percent ionic character or the Pauling scale. The Pauling scale is commonly used to measure the electronegativity difference between two atoms in a bond. Here's a step-by-step explanation of how to calculate the percentage of ionic character in a bond:
1. Determine the electronegativity values of the two bonded atoms. Electronegativity values can be found on the Pauling electronegativity scale. For example, hydrogen (H) has an electronegativity value of 2.2, and oxygen (O) has an electronegativity value of 3.4.
2. Calculate the difference in electronegativity between the two atoms by subtracting the smaller value from the larger value. In this case, the electronegativity difference is 3.4 - 2.2 = 1.2.
3. Use the electronegativity difference to determine the percentage of ionic character using the following equation:
Percentage of ionic character = (1 - e^(-d^2 * c)) * 100
In this equation, "d" represents the electronegativity difference, and "c" represents the conversion factor, which is usually taken as 0.25.
4. Plug in the values into the equation to calculate the percentage of ionic character:
Percentage of ionic character = (1 - e^(-1.2^2 * 0.25)) * 100
Using a calculator, solve the equation and you will find the percentage of ionic character.
Note that the equation used here is an approximation and assumes a linear relationship between electronegativity difference and the percentage of ionic character. The actual ionic character depends on various factors and might not always follow a straight line relationship.
