Find the total number of paramagnetic species among the following?

${\mathrm{Sc}}^{3+},{\mathrm{Fe}}^{3+},{\mathrm{Mn}}^{2+},{\mathrm{Co}}^{4+},{\mathrm{Co}}^{3+},{\mathrm{Cr}}^{+},{\mathrm{Fe}}^{2+},{\mathrm{Mn}}^{3+},{\mathrm{Cr}}^{3+}{\mathrm{Zn}}^{2+},{\mathrm{Ti}}^{+4},{\mathrm{V}}^{3+}$

${\mathrm{Fe}}^{+3},{\mathrm{Mn}}^{2+},{\mathrm{Co}}^{4+},{\mathrm{Co}}^{3+},{\mathrm{Cr}}^{+},{\mathrm{Fe}}^{2+},{\mathrm{Mn}}^{3+},{\mathrm{Cr}}^{3+},{\mathrm{V}}^{3+}$are paramagnetic because of the requirement of unpaired electrons in their orbitals.

Paramagnetic species, is the species having all the electrons linked up in every subshell of the orbital.
