Answer:
1. Ionic Compound
2.Lithium Oxide
3. Li2O
Step-by-step explanation:
This is an Ionic Compound because (Lithium) the metal or cation is giving away electrons to the oxygen a nonmental or anion so both can have a full valence electron shell or have all the electrons on the outer most shell.
This is also Lithium Oxide because the metal goes first then the nonmetal and the ending of the non metal is ending with an ide.
The chemical formula is the periodic table symbols (usually the metal first) and then the charges are switched. E.g Sample A has charge of 3 and sample B has a charge of 2. The formula would be A2B3. If the charge is 1 then you can leave it blank because it is understood. E.g is sample B had a charge of 1 then it would be AB3
