Answer:
K₂O +2Li --> Li₂O +2K
Explanation:
On the left side, K has 2 atoms and O has one combines with Li having 2 atoms. When the process starts Li burns and got atoms from O.
Hence O has 2 ions and Li has 1 ion
so to complete the bond, Two Li will have 2 ions which can complete O by sharing his 2 icons. i.e. Li₂O
and Two atoms of K can exist like 2K
So the equation will be like
K₂O +2Li --> Li₂O +2K
