Determining Amphoteric Compounds

Postby AnuPanneerselvam1H » Fri Dec 08, 2017 2:49 am

How do you determine whether is amphoteric by looking at its formula? Are all compounds with metalloids considered amphoteric?

from my understanding, it is amphoteric if you can draw a diagonal on the periodic table from a nonmetal to a metal, or a metal to a nonmetal.

HI! In addition, it may be helpful to know a couple of the amphoteric oxides so they are easier to recognize. The textbook gives the example of BeO, Al2O3, Ga2O3, GeO2, As2O3, In2O3, SnO and SnO2, Sb2O3, PbO and PbO2, and finally Bi2O3. Hope that helps :)

amphoteric is when it can react with acids and bases right?
