What ionic compound forms between lithium (charge 1+) and oxygen (charge 2-)?

The ionic compound that forms between lithium (Li) with a charge of 1+ and oxygen (O) with a charge of 2- is Lithium Oxide (Li2O).

Here's the step-by-step process:

1. Identify the ions: Lithium (Li) is a metal that forms a cation (positive ion) with a charge of 1+. Oxygen (O) is a non-metal that forms an anion (negative ion) with a charge of 2-.

2. Write the symbols and charges: Li^1+ and O^2-

3. Balance the charges: The total positive charge from lithium must equal the total negative charge from oxygen. Since oxygen has a 2- charge, we need two lithium ions to balance one oxygen ion.

4. Write the formula: The formula is written as Li2O, which means there are two lithium ions for every one oxygen ion.

So, the ionic compound formed between lithium and oxygen is Lithium Oxide (Li2O).
