Bell metal is an alloy of
$Cu,\,Zn$ and $Sn$
$Cu,\,Zn$ and $Ni$
$Cu$ and $Zn$
$Cu$ and $Sn$
Which of the following electronic configuration would be associated with the highest magnetic moment?
Complex ion is shown by
Transition metals show paramagnetism
Among $Co ^{3+}, Ti ^{2+}, V ^{2+}$ and $Cr ^{2+}$ ions, one if used as a reagent cannot liberate $H _{2}$ from dilute mineral acid solution, its spin-only magnetic moment in gaseous state is $......B.M$. (Nearest integer)
Magnetic moment of $x^{n+}$ is $\sqrt {24} $ $B.M.$ Hence No. of unpaired electron and value of $'n'$ respectively. (Atomic number $= 26$)
