  • Greetings of the day!
    Faced the same question from students the day I start f-block elements...

    Well, as per my opinion, It would be more correct to keep La-Yb in f-block; where the f-subshell is 'supposed' to be complete - as suggested by our Madelung rule too; let Lu be regarded a d-block element

    The same be applied to Ac-No to be kept in f-block; although I just learned its last electron to be going into 7p [we probably do not have a choice with it]

    Thanks for putting it forward for a solution/suggestion
