Electronegativity Difference

Which of the following ordered pairs of elements has the highest difference in electronegativity?

• Li and Be

• Li and F

• O and F

• F and F

Which of the following correctly identifies which has the higher electronegativity, Sn or Te, and supplies the best justification?

• Sn, because of its higher nuclear charge

• Sn, because of the closer distance between nucleus and bonded electrons

• Te, because of its higher nuclear charge

• Te, because of the closer distance between nucleus and bonded electrons
