A student calculates the percentage of ionic character in various salts. Which pair of elements forms the most purely ionic bond in the periodic table?
Q1. A student calculates the percentage of ionic character in various salts. Which pair of elements forms the most purely ionic bond in the periodic table?
Answer: CsF
Explanation: The bond between Cesium and Fluorine is the most ionic due to the largest electronegativity difference; LiF is tempting but has a smaller difference.
