[quote=hannah_rhia19]i think, it's not correct.. here; so, here's how to get a lewis structure.. we know that ClO3 is a covalent bond.. right.. 1. get the total valence electron of clo3 which is 25. 2. multiply the subscript by 8 because it's non hydrogen. 8x4=32. 3. subtract your answer in #2 to #1. 32-25=7.[total bonding electron] 4.divide 7 by 2, to get the number of bond lines.. which is 4.. O ll 5. O-Cl-O 6. subtract your answer in #1 to #3. so 25-7=18.. so 18 is the no. of electrons that do not participate during bonding.. so, ikaw na bahala maglagay nung mga dots.. dapat 18 ah..[/quote] ^ wow! your good pala in bonding. damn! that's my worst in chemistry. that's reason why I get low scores. i'm not good with that.
