Electronegativity difference

• What is the electronegativity value of oxygen?

  3.44
• Hydrogen has a higher electronegativity than oxygen.

  False
• Steps to calculate the electronegativity difference

  1️⃣ Subtract the smaller electronegativity value from the larger one

  2️⃣ Compare the difference to standard ranges to determine bond polarity
• What is the electronegativity difference between oxygen and hydrogen?

  1.24
• What is the electronegativity difference range for a nonpolar covalent bond?

  <0.4
• Match the atom with its partial charge in water:

  Oxygen ↔️ δ-

  Hydrogen ↔️ δ+
• The O-H bond in water is nonpolar covalent.

  False
