Step 1
1 of 3

In this problem, we are asked to illustrate the Lewis dot structure of the given halogens. We must take note that these halogens are formed through polyhalide ions. These are the compounds composed of a group of halogens.

We are given the following halogens to draw,

(a) I$_3^-$

(b) BrCl$_2^-$

(c) ClF$_2^+$

(d) I$_5^-$

To be able to draw each Lewis structure we must take note of each compound's electrons and the bonds they create. We must also take note that since all atoms are halogens, they will have 7 valence electrons each.
