If the electronegativity difference between two atoms forming a chemical bond is 1.7, what is the approximate percentage of ionic character in that bond?
Q1. If the electronegativity difference between two atoms forming a chemical bond is 1.7, what is the approximate percentage of ionic character in that bond?
Answer: 50%
Explanation: A difference of 1.7 on the Pauling scale indicates 50% ionic character. 72% corresponds to a much higher electronegativity difference of 2.1.
