Hey everyone, we're asked to add the lone pairs to the following lewis structures. Now we know that iodine and chlorine are both in our group seven. A And since they're both in our group 7, 8, each should have seven valence electrons surrounding it. So starting off with our chlorine on our first compound, we have 12, 3, 4, 5, 6 and seven. So this will get us to our seven valence electrons for our chlorine. Now looking at her iodine, iodine currently has 1, 2 and three. Now, in order to complete that seven, we'll have to add two lone pairs. So now we have seven. Now going to our right structure, we're going to do the exact same thing except this time we have five of chlorine. So we know that our chlorine is going to have three lone pairs surrounding each one since we have one single bond bonded to our iodine. Now iodine has 1, 2, 3, 4 and five. Aydin has five valence electrons currently, so we'll need to add one lone pair to get to that seven. So these are going to be our final lewis structures. So I hope this made sense. And let us know if you have any questions
