The d-orbital has two electron. So, filling of d-orbitals can be $t^{2}_{2g}$

In $V^{2+}$ d-orbital has three electron. So, the filling of d-orbital can be $t^{3}_{2g}$
Similarly

$Cr^{3+}$ (Ions)	$d^{3}$ (No. of d electrons)	$t^{3}_{2g}$ (Filling of d-orbitals)
$Mn^{2+}$	$d^{5}$	$t^{3}_{2g}, e^{2}_{g}$
$Fe^{2+}$	$d^{6}$	$t^{4}_{2g}, e^{2}_{g}$
$Fe^{3+}$	$d^{5}$	$t^{3}_{2g}, e^{2}_{g}$
$Co^{2+}$	$d^{7}$	$t^{5}_{2g}, e^{2}_{g}$
$Ni^{2+}$	$d^{8}$	$t^{6}_{2g}, e^{2}_{g}$
$Cu^{2+}$	$d^{9}$	$t^{6}_{2g}, e^{3}_{g}$
