Chemistry

Write a formula for the ionic compound that forms between each of the following pairs of elements.

1. aluminum and oxygen Express your answer as a chemical formula.
AlO and Al2O3 and Al2O3 the 2 was the bottom right cornor

and I got this message
Use subscripts to represent the number of each type of atom or ion in a molecule.

2. potassium and oxygen Express your answer as a chemical formula.
K2O2 and KO
and I got this for both answers.

Use subscripts to represent the number of each type of atom or ion in a molecule.
