So let's start out. Your email address will not be published. The halogens include fluorine (F), chlorine (C), bromine (B), and iodine (I). 6. Basically you should ignore the d electrons when drawing a lewis structure. Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. But we have two Iodine atoms, so we need to multiply that by two, giving us a total of 14 valence electrons. We're going to draw the Lewis structure for I2, Iodine gas, a very pretty purple gas.

Count up the valence electrons: 7+(4*7)+1 = 36 electrons. The electron pair geometry around the central atom is _____. They all have 7 valence electrons. The seventh lone pair must be placed on the nitrogen atom. Let's discuss this question. The Iodine has more than 8, but that's OK because it can have an expanded octet. In the Lewis structure for ICl 5 there are a total of 42 valence electrons. We'll just put these on the central atom since that's the only place left for them to go.
