Answer
X is a metal and will form electrovalent compounds only.
X3+ formed is a cation and element 'X' has a valency of +3.
If X3+ combines with oxygen the formula of the product is X2O3.
If the above product in the molten state is electrolysed the ion X3+ will get discharged at the cathode.
The ion X3+ accepts electrons and gets reduced to neutral atoms.
