|---|---|
(P) Gd | (1) Paramagnetic |
(Q) Tm | (2) Diamagnetic |
(R) Eu | (3) Highest atomic radius among given elements |
(S) Yb | (4) Least atomic radius among given elements |
| (5) Can show +2 oxidation state |
Options:
Answer:
B
Solution:
Gadolinium has half-filled stability → strongly paramagnetic .
Thulium shows paramagnetism and has relatively smaller atomic radius trend .
Europium is relatively larger in size and can show +2 oxidation state .
Ytterbium is diamagnetic (4f¹⁴ fully filled) and can show +2 oxidation state .
Hence correct matching follows the trend of lanthanoid contraction and f-electron stability.
