Explanation: Chromium in [Cr(NH3)6]3+ is in +3 oxidation state and has electronic configuration of [Ar]3d54s1. Cr3+ ion provides six empty orbitals to accommodate six pairs of electrons from six molecules of ammonia. … Due to the presence of these unpaired electrons in the complex it is paramagnetic in nature.

Likewise, How many unpaired electrons would you expect for manganese in kmno4 or diamagnetic material?
Paramagnetism: Oxidation States of Manganese – Potassium Permanganate. Potassium permanganate is diamagnetic and is not attracted to a magnet. Manganese(III) oxide, with 4 unpaired electrons per Mn atom, is more strongly attracted to a magnet than is manganese(IV) oxide, with only 3 unpaired electrons per Mn atom.

Which out of Cu2+ fe3+ and Cr3+ has the highest paramagnetism?
Fe2+ has the highest paramagnetic character followed by Cr3+ and least is for Cu2+. μ = n ( n + 2 ) where n is the number of unpaired electrons. among these three, Fe2+ has the maximum paramagnetism, then Cu2+ and then Cr3+.
How do you find unpaired electrons?
Once you figure out the electron configuration, you fill up the corresponding orbitals with electrons, any left with one is considered unpaired. Since 1s can only hold 2 electrons, and P has 15, that’s obviously filled and has no unpaired electrons. The same is for 2s which holds 2, 2p which holds 6, 3s which holds 2.

Why does CR have 6 unpaired electrons?
Six unpaired electrons. … Thereis only a small energy difference between the 4s and 3d orbitals, so it isnot hard, from an energy standpoint, for a 4s electron to move to a 3d orbital.
What is the electron configuration of Cr3+?
The electronic configuration of Cr having atomic number of 24 is 1s22s22p63s23p64s13d5 which is half-filled d-orbital. Cr3+ has 3 electrons removed from the outermost shell. Therefore, the electronic configuration comes out to be [Ar]3d3.
Which is more paramagnetic Fe3+ or Cr3+?
Answer Expert Verified Fe³⁺ will be more paramagnetic. … Hence it is paramagnetic. Fe²⁺ has no free electrons. Hence it is diamagnetic in general.
