- Interesting. Of course, current layout is the regular layout for periodic table(s). Do you have any example or source that switches these two (transpone)? Would it make the essence more clear? -DePiep (talk) 08:33, 7 August 2014 (UTC)

I don't see why Fr should have no value and I haven't heard a good explanation. What is it?
By the way, if you draw a horizontal line from Fr dot to the scale line, you'll see that both Fr's and Cs's values are closer to 0.5 than to 1.0. So again, ~0.8 remains unreferenced.--R8R (talk) 12:32, 23 August 2016 (UTC)
