MCQ
The outer electronic structure of lawrencium (atomic number $103$) is
  • A
    $Rn\,\, 5f^{13} \,7s^2 \,7p^2$
  • B
    $Rn\, \,5f^{13}6\,d^1 \,7s^1\, 7p^2$
  • C
    $Rn\,\, 5f^{14}\, 7s^1 \,7p^2$
  • $Rn\, \,5f^{14} \,6d^1\, 7s^2$

Answer

Correct option: D.
$Rn\, \,5f^{14} \,6d^1\, 7s^2$
d
Lawrencium $-\,103$

Lawrencium is an Actinide present in $5 f$ series of $f$-Block elements.

The outermost configuration $=\left[Rn\right]\, 5 f^{14} \,7s^2 \,7 p^1$
