Question

question 8 of 25 which sentence describes two atoms that form an ionic bond? a. the difference in their electronegativities is less than 1.7. b. each atom has a small electronegativity. c. the difference in their electronegativities is greater than 1.7. d. each atom has a large electronegativity.

Explanation:

Step1: Recall ionic - bond concept

Ionic bonds form between atoms with a large electronegativity difference.

Step2: Identify the threshold

When the electronegativity difference between two atoms is greater than 1.7, an ionic bond is likely to form.

Answer:

C. The difference in their electronegativities is greater than 1.7.
