The correct 4f sub-shell electronic configuration of $Yb^{2+}$ ion is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $4f^{14}$
Ytterbium (Yb) has atomic number 70.
- Ground-state electronic configuration of Yb:
$[Xe]\,4f^{14} 6s^2$
- For Yb²⁺, it loses 2 electrons (from 6s orbital):
$Yb^{2+} : [Xe]\,4f^{14}$
