    Two major things learned in this video:
    + What is lanthanoid contraction.
    + Never underestimate a 3 min video.

    Mam you are great 👍.
    In simple terms .. lanthanoids and actinides are exception to the case, in which moving from top to bottom radius increases, but it don't increase rather decrease or remain constant in these two dumb series due to shielding.

    can anybody please help as I still did not get the lanthanoid contraction as I have studied from the books that Z eff increases the down the period and hence the size decrease and it is applicable to the starting of the periods from 1 and from what I am able to understand lanthanoid contraction is exactly the same meaning so what is the difference? is it called lanthanoid contraction because it is only applicable d and f block series???

  • @sarangbishnoi29

    Mam I have a question
    Even having 3d5 electron configuration ( a half filled electron configuration and 5 unpaired electrons ) why Manganese has lowest melting point and energy of atomisation

    • @nikhiltiwari5707
      @nikhiltiwari5707 Год назад

      As manganese has half filled orbital electrons are held tightly by the nucleus so that delocalisation is less and metallic bond is much weaker than preceding elements.
