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!
