Calculate the magnetic moment of a divalent ion in aqueous solution if its atomic number is $25$
Solid $CuSO_4·5H_2O$ having covalent, ionic as well as co-ordinate bonds. Copper atom/ion forms ................. co-ordinate bonds with water.
For the first row transition metals the ${E^\Theta }$ values are:
${E^\Theta }$ | $V$ | $Cr$ | $Mn$ | $Fe$ | $Co$ | $Ni$ | $Cu$ |
$\left( {{M^{2 + }}/M} \right)$ | $-1.18$ | $-0.91$ | $-1.18$ | $-0.44$ | $-0.28$ | $-0.25$ | $+0.35$ |
Explain the irregularity in the above values.
Although fluorine is more electronegative than oxygen, but the ability of oxygen to stabilize higher oxidation states exceeds that of fluorine. Why ?
