**Alcl3 Lewis Structure**

### What is the Lewis structure of aluminum trichloride? The answer is?

Since aluminum has only 3 valence electrons, its byte does not have two electrons. This means that one of the chloride groups must share an additional electronic group with the aluminum. Three of the chlorides can share an extra electron pair with it (that is, they have 2 lines connected by aluminum), so there is resonance. There are 3 to be exact, one for each chloride that divides another pair of electrons with al.

For example, I will do NO2. The Lewis structure is O = NO with two pairs of electrons to the left of O and 3 pairs of electrons to the right of O and one pair of N. It can also be called O = O. So these are two resonant structures. The truth is, N has an average of 1.5 links per o.
