    Lanthanoids fall on f block so they sheild the valence electrons poorly out of all orbitals which means that the nucleus has a tight hold of valence electrons i.e. the effective nuclear charge increases. Therefore with increase in z eff the atomic radius decreases ehich is known as lanthanoid contraction.

    Canadian President aNd PM (at) Same European Golden Table. ये किसका ट्रिक है
    ये इंटरनेट पर है!
    "Canadian President and PM at Same European Golden Table" appears to be a mnemonic or memory aid to remember the order of the lanthanide elements in the periodic table. Each word or phrase in the sentence corresponds to the symbol of a lanthanide element in the correct order. Here's how it breaks down:
    Canadian: Ce (Cerium)
    President: Pr (Praseodymium)
    and: Nd (Neodymium)
    PM (Prime Minister): Pm (Promethium)
    at: Sm (Samarium)
    Same: Eu (Europium)
    European: Gd (Gadolinium)
    Golden: Tb (Terbium)
    Table: Dy (Dysprosium)
    So, when you take the first letter of each word in the sentence, you get the sequence of the lanthanide elements in the periodic table: Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy.
