Thank you for your question! Reacting sodium (Na) with oxygen (O) would give you a compound called sodium oxide. Because you are starting with charged ions (sodium is missing an electron and oxygen has two extra electrons) you must balance those charges to make your compound. First, we need to note that there is a minor mistake in your equation. Oxygen is usually a -2 charge not a +2. So, if you have a sodium with one positive charge (Na +1) and an oxygen with two negative charges (O -2) you would need two sodium atoms each with one positive charge to be opposite of the one atom of oxygen with two negative charges. Here is an equation to show you a picture of what I am saying: Na(+1) + Na(+1) + O(-2) = 0
So, since your charges are balanced your chemicals would react together in the form 2Na + O = Na2O -- please notice here that the 2 should be a subscript.Notice how I changed the reaction a little bit so that I also balanced the number of each type of atom (2 sodium for one oxygen) When you are doing your reactions remember to balance your atoms and their charges and you should be able to work through the problems. Good luck!
