• A. Bohr model
• B. Rutherford model
• C. Lewis dot structure
• D. Pauling scale

Answer: (D)

Verified step by step guidance

1. Understand that electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
2. Recognize that several models and scales exist to describe atomic structure and properties, such as the Bohr model (which describes electron orbits), the Rutherford model (which describes the nucleus and electron cloud), and Lewis dot structures (which represent valence electrons).
3. Identify that while these models help explain atomic structure and bonding, they do not provide a quantitative scale for electronegativity.
4. Learn that the Pauling scale is the most commonly used quantitative scale for electronegativity, developed by Linus Pauling, which assigns numerical values to elements based on bond energies.
5. Conclude that the Pauling scale is the standard model used to quantify electronegativity values across the periodic table.
