Peroxide (O22¯ is a polyatomic ion and it will be discussed in more detail later. I decided to mention it here because I'm quite sure the peroxides of #18 and #20 exist, but they are somewhat unusual compounds. Be aware that a teacher may try to trip you up with one of them, as in this sample test question.

What is the name for PbO2?
(a) lead(II) oxide
(b) lead oxide
(c) lead peroxide
(d) lead(II) peroxide
(e) lead(IV) peroxide

I might just use that question on my test!
