If you need to cite this page, you can copy this text.

I am not able to figure out the reason for this error. Although groups generally have more significant periodic trends, there are regions where horizontal trends are more significant than vertical group trends, such as the fblock, where the lanthanides and actinides. So, the frequency was set to 1 which looked logically correct. Periodic table the basis of the periodic system britannica. The history of the periodic table chemistry master.
