Sagot :

Answer:Li2O

Explanation:  Lithium is an alkali metal in Group 1.  It has a single valence electron that it would be pleased to give up, or share, with another element.  Oxygen is in Group 16, just one removed from the halogens.  It has 6 valence electrons, and wants 2 mosr to complete it's valence shell.  One lithium will contribute 1 electron, so oxh=ygen will keep looking for a second.  If another lithium is available, it will react with that one also, resulting in Li2O.
