Question
Which of the following pairs will form the most stable ionic bond?
A.
$$Na\,\,{\text{and}}\,Cl$$
B.
$$Mg\,\,{\text{and}}\,F$$
C.
$$Li\,\,{\text{and}}\,F$$
D.
$$Na\,\,{\text{and}}\,F$$
Answer :
$$Mg\,\,{\text{and}}\,F$$
Solution :
The ionic bond between $$Mg$$ and $$F$$ is most stable because in these the electrostatic force of attraction is maximum. As $$Mg$$ has high electropositive character and $$F$$ has high electronegative character among all other options that are given in question.
