Verified step by step guidance

Understand the concept of electronegativity: Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The higher the electronegativity, the greater the atom's ability to attract electrons.

Identify the electronegativity values: Use a periodic table or a chart of electronegativity values to find the electronegativity of each element involved in the pairs given in the problem.

Calculate the difference in electronegativity for each pair: Subtract the smaller electronegativity value from the larger one for each pair of elements. This will give you the difference in electronegativity for each pair.

Compare the differences: Once you have the differences in electronegativity for each pair, compare them to determine which pair has the greatest difference.

Conclude with the pair having the greatest difference: The pair with the largest difference in electronegativity is the one where the difference is the greatest. In this case, it is K and F.
