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

The reaction of formation of ions by fluorine and potassium​ is .

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 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 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.

Thus, we can conclude that the reaction of formation of ions by fluorine and potassium​ is .

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
