All of the above.

Vedclass · Answer

(D) $1$. The stability of the $+3$ oxidation state generally decreases across the $3d$ series as the nuclear charge increases,making it harder to remove the third electron.$2$. In the $3d$ series,from $Cr$ $(Z=24)$ to $Cu$ $(Z=29)$,the atomic radii remain almost constant because the increase in nuclear charge is balanced by the shielding effect of $d$-electrons.$3$. The stability of the $+2$ oxidation state increases across the period because the ionization energy required to remove two electrons increases,but the hydration energy or lattice energy compensates for this,making the $+2$ state more common for later elements like $Ni^{2+}$ and $Cu^{2+}$.
