oxygen has a larger electronegativity than fluorine.
true
false

Explanation:

Question 1

Linus Pauling created the first electronegativity scale. Niels Bohr is known for atomic model, Leonard Pron and Cohen are not associated with electronegativity scale creation.

Ions are formed when neutral atoms gain or lose electrons to achieve stability (like noble gas configuration) for bonding. This matches the definition of ion formation.

Fluorine is the most electronegative element, having higher electronegativity than oxygen. So oxygen's electronegativity is less than fluorine's.

Answer:

A. Linus Pauling
