Fun Pa, Protactinium Flag - Element 91

What do you get when you put tin into an active pro-league category of elements?  Protactinium!  What a mouthful.  Strange thing about this element is that it uses the same letters for its abbreviation as does Pennsylvania, 'P' and an 'A.'  The flag has the year 1913 in the lower green field of the shield since this element was discovered in 1913.  In the middle is a flag of Germany to honor one of its fathers Oswald Helmuth Göhring while the other father was from Poland, Kasimir Fajans, who gets an double honor on the lower red ribbon in the compartment.  Also on the lower ribbon is the name of the element—Proctactinium.  In the upper part of the shield is the atomic number 91 and the two letter symbol Pa.  Instead of the North American Bald Eagle in the crest position, a white atom has taken its place.
