I recall the formula μ = √[n(n+2)] BM for spin only magnetic moment, but I keep confusing it with magnetic susceptibility because my mind is tired from late-night delivery runs for my beta's engineering fees. For Fe2+, Ni2+, Mn2+, you count unpaired electrons, yet I see it like measuring the weight of my groceries on bumpy village roads—not so straightforward. Actually, I feel these calculations lack the real-life weight, like my chai growing cold while I race against sunrise, so they don't capture the full story.
