What are some elements that can combine with oxygen
there are many elements that can combine with O2, atomic number 8. hydrogen and oxygen make water, or H2O. and you can mix lithium as well, making lithium oxide. depending on how much you mix and how you mix it you can get different things with many things.
oxygen has 3 things to connect it to other things like if you burn calcium you get calcium oxide... this happens if you burn anything
Most metals that rust react with oxygen to form a metal-oxide. Iron is an example.
The list does go on...
Hydrogen and Oxygen itself to make Ozone
