Question
Write Lewis structures for these molecules or ions.(a) CIF(b) $\mathrm{H}_{2} \mathrm{Se}$(c) $\mathrm{BF}_{4}^{-}$(d) $\mathrm{PO}_{4}^{3-}$
Step 1
For ClF, both chlorine and fluorine are in group 7, so they each have 7 valence electrons. For H2Se, hydrogen has 1 valence electron and selenium has 6. For BF4-, boron has 3 valence electrons, each fluorine has 7, and the negative charge adds 1 more. For PO43-, Show more…
