Magnetic moment of\[C{{u}^{+}}\]is

A)  2.59               

B)  0

C)  3.2              

D)  5.1

Correct Answer: B

Solution :

 \[C{{u}^{2+}}=3{{d}^{10}},4{{s}^{0}}\] Unpaired electron is not present in\[C{{u}^{+}}\]ie, \[n=0\] Magnetic moment\[=\sqrt{n(n+2)}\] where,\[n=\]Number of unpaired electrons. magnetic moment of \[C{{u}^{+}}=\sqrt{0(0+2)}\] \[=0\]
