Answer:

The results is Li₂O

Step-by-step explanation:

n a chemical reaction, the electron miner in the formula must be balanced, that is, the number of positive and negative charges is the same

In this case, oxygen has a valence of -2 that is, it can give two electrons and lithium has a valence of +1, therefore two lithium atoms are needed for the charges to be neutral, therefore the chemical formula is

The results is Li₂O
