Final answer:
The percent ionic character of a bond is a measure of how much the bond resembles an ionic bond. It is related to the difference in electronegativity between the bonded atoms. No bond has 100% ionic character.
Step-by-step explanation:
The percent ionic character of a bond is the measure of how much the bond resembles an ionic bond. It is a way to quantify the degree of electron sharing or transfer between two atoms.
The percent ionic character is related to the difference in electronegativity between the two atoms in the bond. The larger the electronegativity difference, the greater the percent ionic character. However, no bond has 100% ionic character due to the nature of covalent bonds, where electrons are shared between atoms.
