An example of an oxide is rust which is the oxide of iron, it's usually when a metal has been left exposed to oxygen, but that's not the limit by any means. Anyways to answer your questions
Na typically has a +1 charge, and oxygen will have a -2 charge, so we need two Na for every one oxygen
Na2O
Calcium has a 2+ charge so we can get a 1:1 ratio here
CaO
Aluminum I think I remember has a +3 charge, but look that up. So first we have to make +3 even, so we need two aluminums, leaving us with a +6 charge. That means we need three O2- to balance out the charge giving us
Al2O3
Hope that helps

An oxide is a chemical compound containing at least one oxygen atom as well as at least one other element. Most of the earth's crust consists of oxides. Oxides result when elements are oxidized by air. Combustion of hydrocarbons affords the two principal oxides of carbon, carbon monoxide and carbon dioxide.
Sodium oxide with chemical formula of (Na2O)
Calcium oxide with chemical formula of (CaO)
Aluminum oxide with chemical formula of (AIO)

Oxides are just compounds of another element and oxygen.
The formulas for these oxides are Na2O, CaO and Al2O3.
