Question

which of the following values best classifies a bond between 2 atoms as being ionic? a. an electronegativity difference of less than 1.7 between the atoms b. an electronegativity difference of greater than 1.7 between the atoms c. an electronegativity difference of less than 2.7 between the atoms d. an electronegativity difference of greater than 4.7 between the atoms

Explanation:

In chemistry, a bond between two atoms is considered ionic when the electronegativity difference between them is greater than 1.7. This large difference leads to one atom effectively "stealing" an electron from the other, forming ions.

Answer:

B. An electronegativity difference of greater than 1.7 between the atoms
