the the transition metal X form an oxide of formula X2O3. it is found that only 50% of X atoms in the compound iron + 3 oxidation state

Answer 2

Answer:

$\huge\mathcal\color{teal}Answer$

According to Slaters equation for calculating effective nuclear charge (Z*=Z-S), 3d orbital of Cobalt has a value of 6.90. Clement et.al in 1963 proposed a modified version of Slaters rules and according to them it is found to be 11.855.
