Question

Two elements X and Y combine to form a compound XY. Under what conditions the bond formed between them will be ionic?

• A. If the difference in electronegativities of X and Y is $1.7$.
• B. If the difference in electronegativities of X and Y is more than $1.7$.
• C. If the difference in electronegativities of X and Y is less than $1.7$.
• D. If both X and Y are highly electronegative.

Answer 1

Answer: (B)

If the difference in electronegativities of X and Y is more than $1.7$.

Answer 2

: For the formation of an ionic bond, the electronegativities of two atoms should differ by more than $1.7$.
