Answer: C, 13) How many valence electrons are in the nitrate ion? Where should the non-essential passengers stand during the fueling process? The O=Cl-O bond angle is 109.5, while all the Cl-O bond lengths are 144 pm in [ClO, It is due to the resonance present in the perchlorate [ClO, -1 formal charge is present on a single bonded O-atom in the [ClO. Three of them will overlap with the 3p orbital of the chlorine atom and form three sigma bonds. Therefore, lone pair-bond pair electronic repulsions exist in the molecule in addition to bond pair-bond pair repulsions. The [ClO4] ion consists of 1 Cl-atom, 4 O-atoms and it also carries a negative (-1) charge which means 1 extra valence electron.
