All the following statements about the transitional elements are true except that
All of the transitional elements are predominantly metallic
In aqueous solution many of their simple ions are coloured
Most of the transitional elements show pronounced catalytic activity
Most of the transitional elements show only one valence state
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.
