They don't have group numbers assigned to them. Towards the middle of the PT elements in vertical groups don't have properties that are very similar so group labels are less useful. groups at the ends contain strikingly similar elements, and are even given names e.g. Noble Gases, as well as numbers.
back then, how could they arrange the atoms based on ratios and have the atomic number stay the same ? so pretty much they organized the elements based on the proton no. without knowing the proton number?
Belong Lanthanides and Actanides to groupgrpup 2 or to group 3?

Very educational. Thank you
You are welcome!
Finally I understand 😂
Great, Sunil!
What a easy soft demo.. makes it very easily understandable.
Great :)
Making things easy Visual learning (that's me) !
I hope so :)
