Which element forms an ionic compound when it reacts with lithium?
creativ13 [48]
<h3>Answer:</h3>

              Br (Bromine)

<h3>Explanation:</h3>

Li and K,

As the electronegativity difference between Li and K is less than 1.7 therefore, ionic bond cannot form between these two metals.

Li and Fe,

The electronegativity difference is less than 1.7 so neither electron loss nor electron gaining will take place between these two metals. Therefore, there will be no ionic bond between them.

Li and Kr,

As Krypton is a noble gas and does not react due to complete octet hence the formation of KrLi is difficult. However, Krypton can make compounds like KrF₂ e.t.c. Therefore we can skip this option.

For Li and K,

                   E.N of Bromine             =   2.96

                   E.N of Lithium               =   0.98

                                                             ________

                   E.N Difference                     1.98          (Ionic)

This ionic compound is possible and is the correct option because ionic compounds are always made by metals and non metals and here the combination is perfect.

<h3>Conclusion:</h3>

                          Lithium (a metal) and form Ionic bond with Bromine (a non metal)
