Phosphorus is not an oxide. It is an element. It is a nonmetal.
metal oxide plus water makes a base example: NaO + H2O ==> 2 NaOH nonmetal oxide plus water makes an acid example: CO2 + H2O ==> H2CO3
A non metal oxide is a compound of a non metal with oxygen.metals are in the center or left hand side of the periodic table of chemical elements.non metals are to the right hand side and are...
They are the product of when nonmetal elements are oxidized by oxygen such as CO2, SiO2, etc.
zinc oxide would be ionic (so it would be polar as in it has 2 poles)
