Question

An ionic bond is most likely to form between two elements that have a difference in electronegativity values of Select one: a. 0.1. b. 1.5. c. 3.0. d. Both (a) and (b)

Answer 1

Answer: option C) 3.0

Explanation:

The electronegative value of an element indicates the power of its atom to attract an electron. It ranges from 0 to 4.

Ionic bond is formed between two elements with WIDE difference in electronegative values. e.g Sodium with 0.93 and Chlorine with 3.16 forms an ionic bond in NaCl with a difference of 2.23

Thus, a difference of up to 3.0 makes an ionic bond
