(A) The electronic configuration of the ion $X^{+3}$ is $[Ar]3d^4$.The total number of electrons in $X^{+3}$ is $18 + 4 = 22$.Since the element $X$ is in the $+3$ oxidation state,it has lost $3$ electrons to form the $X^{+3}$ ion.Therefore,the atomic number of the neutral element $X$ is $22 + 3 = 25$.
