    1. The problem statement, all variables and given/known data
    Mn+2 has a higher magnetic moment than Fe+2 but practically Fe+2 is ferromagnetic right? So more magnetic right?

    2. Relevant equations
    ## μ = √ (n(n+1))##

    3. The attempt at a solution
    For the Mn ion it comes to be √35 and for the ferrous ion √25
    So yes Mn+2 is more paramagnetic but Fe+2 is more magnetic as a solid right?
    I really don't know why
    Could it be the alligator of the atoms in the solid?

    Metallic solid iron is ferromagnetic and this is a complicated effect involving the interaction of the atoms. It makes no sense to say that ferrous ions are ferromagnetic.

    Ok Between Fe2+ or Mn2+
    Which one produces a stronger magnetic field? Fe2+ right?
