some amphoteric oxides are:-

  1. zinc oxide
  2. aluminium oxide
  3. lead oxide (PbO)
  4. tin oxide(SnO)
  5. Antimony oxide(Sb2O3)
  6. Vanadium oxide (V205)
  7. Chromium oxide (Cr203) . And some acidic oxides are- Carbon dioxide, nitrogen dioxide, sulphur dioxide, chromium oxide (CrO3), manganese (VII) oxide, phosphorous pentaoxide etc. In conclusion non metals generally form acidic oxides in contrast to metals which either form basic or amphoteric oxides.
 
Hope it helps
