Amphoteric - BeO

Postby Shannee Mak 3F » Sat Dec 09, 2017 2:42 am

Can someone explain to me why BeO is amphoteric? I would assume that it would only be a basic oxide, but the book says it is amphoteric. Why is this?

There are several exceptions around the metalloids that are also considered amphoteric. These are on page 469 and include Be, Al, Ga, In, Sn, Pb, Bi.
