Which of the following magnetic moment values will corresponds to highest ionization energy for $Mn$
$2\sqrt 2 $
$\sqrt {15} $
$\sqrt {35} $
$\sqrt {24} $
Magnetic moment of $x^{n+}$ is $\sqrt {24} $ $B.M.$ Hence No. of unpaired electron and value of $'n'$ respectively. (Atomic number $= 26$)
In the series $Sc(Z = 21)$ to $Zn(Z = 30)$ , the enthalpy of atomization of _____ is the lowest
Although $\mathrm{Cr}^{3+}$ and $\mathrm{Co}^{2+}$ ions have same number of unpaired electrons but the magnetic moment of $\mathrm{Cr}^{3+}$ is $3.87$ $B.M.$ and that of $\mathrm{Co}^{2+}$ is $4.87$ $B.M.$ Why ?
Mercury is the only metal which is liquid at ${0\,^o}C$. This is due to its
