For which of the following transition metal ion is shown highest magnetic moment having outer electronic configuration
$3{d^1}$
$3{d^8}$
$3{d^5}$
$3{d^7}$
German silver is an alloy of
Solid $CuSO_4·5H_2O$ having covalent, ionic as well as co-ordinate bonds. Copper atom/ion forms ................. co-ordinate bonds with water.
$\operatorname{Zr}\,(\mathrm{Z}=40)$ and $\mathrm{Hf}\,(\mathrm{Z}=72)$ have similar atomic and ionic radii because of :
Magnetic moment of $x^{n+}$ is $\sqrt {24} $ $B.M.$ Hence No. of unpaired electron and value of $'n'$ respectively. (Atomic number $= 26$)
The addition of metals like $Cr,\,Mn,\,W$ and $Ni$ to ordinary steel makes it
