The chemist who produced the first electronegativity values, by comparing energies needed to break different bonds, was:
AJohn Dalton
BRobert Boyle
CLinus Pauling
DMarie Curie
Answer & Solution
Correct answer: C. Linus Pauling
1. He needed a measurable route into an abstract idea.
2. Bond breaking energies gave him numbers he could compare across elements.
3. That chemist was Linus Pauling.
