In the opening credits, the "Br" and "Ba" in "Breaking Bad" are presented as if they are entries from a periodic table of elements. The additional pieces of information included are atomic number, atomic mass, oxidation states, and electron shell configuration. Each of these is depicted accurately for both Br (bromine) and Ba (barium), except the electron shell configuration for Ba is copied verbatim from Br. Oddly, the periodic table that the entry for Ba is visually extracted from contains the correct information. However, the creators were most likely aware of this, but thought the opening had enough merit to warrant this disregard for correctness under artistic license.
In Walter White's back yard you will notice an outline of a fire place right by their sliding back door, but inside the reverse wall is the dining room/kitchen. Their fire place inside should be on the side of the house.
In the opening credits letters in the names are highlighted in green so as to represent a chemical element symbol. However, Michael Slovis, the Director of Photography, for several of the beginning episodes, they highlight the Ch. There is no chemical element symbol Ch. After a number of episodes they caught it and thereafter they only highlighted the C.
In multiple episodes the view in the rear view and side mirrors is reversed from what it should be. It makes the driver in the trailing car appear to be sitting in the right front passenger seat of the car.
