Question

Which among the following is the most stable?

• A. $T{i}^{2+}$
• B. $T{i}^{3+}$
• C. $T{i}^{4+}$
• D. All are equally stable

Answer 1

The correct option is C $T{i}^{4+}$

Electronic configuration:
$T{i}^{2+}:\left[Ar\right]3d^{2}4s^0$
$T{i}^{3+}:\left[Ar\right]3d^{1}4s^0$
$T{i}^{4+}:\left[Ar\right]3d^{0}4s^0$
Since $T{i}^{4+}$ attains a inert gas configuration , it s the most stable,
