Which of the following is a product formed when k reacts with cl2? kcl k2cl kcl2 k2

KCl

Explanation: Potassium [K]  has an atomic no of 19 and the electronic configuration is:

tends to get stable by losing one electron and forming

Chlorine [Cl] has atomic no of 17 and thus the electronic configuration is :

tends to get stable by gaining one electron and forming

and attract each other and form an ionic bond. As we have a chlorine molecule that is two atoms of chlorine are present, 2 atoms of potassium will react to form 2 moles of KCl.

your answer would be “dry”
