The atomic number of $\text{Ti}$ is $22$.

Electronic configuration of $\text{Ti}$ is $[\text{Ar}]3d^{2}4s^2$.

Electronic configuration of ${\text{Ti}}^{2+}$ is $[\text{Ar}]3d^2$.

Number of unpaired electrons, $n=2$.

Spin-only magnetic moment, $\mu =\sqrt{n(n+2)}\text{ BM}$.

$\mu =\sqrt{2(2+2)}=\sqrt{8}\approx 2.84\text{ BM}$.

Answer: $2.84$ BM
