I am still a bit unclear on how and why the metalloids on the periodic table are amphoteric?
Can anyone show me quick methods to determine whether something is amphoteric or not?
Thank you.

Re: Amphoteric Compounds and Periodic table
Hello! So in general something is amphoteric if it is able to react both as a base and an acid. So specifically, what I look out for is a negative charge on the compound, along with a hydrogen atom. This more pertains to your second question than your first, but I hope that this is helpful!

Yes, this is very helpful. Is that always the rule or are there any exceptions?
Re: Amphoteric Compounds and Periodic table
They are amphoteric because they can act as an acid or a base! (Gaining Proton or Giving off a positive charge because they have H from water)
