Question

write the recation of formation of ions by fluorine and potassium​

Answer 1

Answer: The reaction of formation of ions by fluorine and potassium​ is $K^{+} + F^{-} \rightarrow KF$.

Explanation:

Atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. So, in order to attain stability it needs to lose 1 electron due to which it forms $K^{+}$ ion.

Atomic number of fluorine is 9 and its electronic distribution is 2, 7. In order to attain stability it needs to gain one electron and hence forms $F^{-}$ ion.

Therefore, when both these ions come in contact with each other then it leads to the formation of KF compound.

The reaction equation for this is as follows.

$K^{+} + F^{-} \rightarrow KF$

Thus, we can conclude that the reaction of formation of ions by fluorine and potassium​ is $K^{+} + F^{-} \rightarrow KF$.
