Welcome to OpenStudy. From the balanced equation, we can see that 4 Li will combine with 2 O.

anonymous · Answer

so for one atom of oxygen, 2 Li will combine?

2 Li for one oxygen check it in the formula itself its Li2O i.e one Oxygen bonds with two Lithium atoms if you still dont get it Check the valencies of both the elements. Lithium has a valency of 1 and is electropositive in nature (donates electrons) whereas Oxygen has a valency of 2 and is electronegative in nature( tends to accept electrons) Hence we would need two lithiums to donate electrons to fulfill OXYGEN!
