(1) Cr3+ , Fe3+ (2) Fe3+ , Mn2+ (3) Fe3+ , Co3+ (4) Sc3+ , Cr3+ Fe3+ and Mn2+ will have the same electron number, that is 23, and will therefore have the same electronic configuration. Was this answer helpful?
Which is more stable Cr2+ or Cr3+?
ANS: (i) It is because Cr2+ loses electron to become Cr3+ which is more stable due to half filled t2g orbitals, whereas Mn3+ will gain electron to become Mn2+ which is more stable due to half filled Page 2 2 d-orbitals. (ii) Manganese.
What is the ground state electron configuration for Cr3+?
