Q. Given the following data: Element Atomic Number Electronegativity Hydrogen 1 2.1 Carbon 6 2.5 Nitrogen 7 3.0 Oxygen 8 3.5 Sulfur 16 2.5 Phosphorus 15 2.1

The element with the highest electronegativity is

The answer is: Oxygen

A step-by-step solution: The element with the highest electronegativity is oxygen. The electronegativity of an element is a measure of its ability to attract electrons. The higher the electronegativity of an element, the stronger its attraction for electrons.
