You can see hydrogen starting in the 1790 after Cavendish realized it was an element. From this graph we would assume that sodium and potassium were discovered around 1810 and sure enough Davy isolated both of them in 1807.
Radium is the interesting one here where we can clearly see its discovery in 1898.
Group 3-Group 12
What I'd like to know is what happened to silver between 1790 and 1810.
Look at 1890. The Hall-Héroult process was put into use in about 1890.
I then took the most used element of each group and pitted them against each other as a battle royal of the elements.
Not surprisingly gold, lead, and iron are the top three with first prise going to iron.
