memorizing amphoteric oxides

[Kylie McCauley 1D]

Hi,

Do we have to memorize the amphoteric oxides for the final? What general things should we memorize for it?

[Kyla Roche 2K]

Yes I believe we have to have a general idea of them. There is a chart online and they are typically near the metalloids on the periodic table.

Here is a picture of the amphoteric oxides for convenience.

Yes, we are supposed to memorize them. In Matthew Tran's workshop, he explained that a metal oxide is usually a base, a nonmetal oxide is usually an acid, and a transition metal oxide is usually an amphoteric compound. The amphoteric compounds generally follow the diagonal line of the metalloids.
