chapter 3 hw #57 question

For part C of question number 57 you have to write the lewis structure for a perchlorate ion. My question is why can't the chlorine atom form four double bonds with all of the oxygens so that the oxygens all have a zero formal charge?

Re: 3.55

BrO IS a radical because it has an odd number of valence electrons, but I think you are confusing #55 and #56 as part D for #55 is not BrO and that is instead part D for #56. Hope that helps! :)
