MCQ
$C{u^{2 + }}$ will have the following electronic configuration
  • A
    $1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^{10}}$
  • B
    $1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^9},4{s^1}$
  • ✓
    $1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^9}$
  • D
    $1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^{10}},4{s^1}$
✓

Answer

Correct option: C.
$1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^9}$
c
(c) Ground state of $C{u^{29}} = 1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^{10}}4{s^1}$

   $C{u^{2 + }} = 1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^9}$.
