1.Aluminum
2.Phosphorus
3.Nitrogen

Waiting for answer, do reply ASAP!!!

P.S Do tell the reason aswell!!

Nitrogen oxide and Phosphorus oxides are acidic because all non metal oxides are acidic.

Aluminium oxide is amphoteric because it has properties of both acids and bases........( reacts with both acids and bases )

xcpt 4 alumunium , barium and zinc ...

 

[wijie1993]

except for aluminium, barium, zinc and strantium

man metalloids make amphoteric oxides... + Al, Pb and Zn are other amphoteric oxides in our syllabus... CO, NO and H20 are Neutral Oxides
