Identify the ionic charge and magnetic nature respectively of manganate ion.

Options

A-1, Diamagnetic
B-2, Diamagnetic
C-2, Paramagnetic
D-1, Paramagnetic

Correct answer

C. -2, Paramagnetic

Step-by-step solution

Manganate ion is paramagnetic due to presence of unpaired electron. Chemical formula for manganate and permanganate ion respectively are Mn2-4 and mnO-4. Thus, the ionic charge of manganate and permangante ion are respectively -2 and -1.25-
