Why do all the Period 3 elements in their oxides exist in positive oxidation states?
the reaction is exothermic
Oxygen has a lower electronegative value
Oxygen has a higher electronegative value
the oxygen is a non metal
An ionic bonding by an element with oxygen (to make an oxide) is more likely created when...
when they are heated together
there are more electrons
Van der Waals is greater
the difference of electronegativity is large
