Answer:
The Fe^{+2} ion is more paramagnetic.
explanation
The atomic number of copper element is, 29
The general electronic configuration of Cu is,
The electronic configuration of will be,
The number of unpaired electrons in = 1
The atomic number of iron element is, 26
The general electronic configuration of Fe is,
The electronic configuration of will be,
The number of unpaired electrons in = 4
The atomic number of chromium element is, 24
The general electronic configuration of Cr is,
The electronic configuration of will be,
The number of unpaired electrons in = 3
As we know that the more number of unpaired electrons, the more will be the paramagnetic. The ion has the 4 number of unpaired electrons. So, it is more paramagnetic.
