Talk:Ulvöspinel

Charge
The charge for Iron in Ulvöspinel is 3+, not 2+.

All members of the spinel group have 2 3+ ions and 1 2+ ion. I am going to change it, if you can find some evidence to point against this, please post your rationale. —Preceding unsigned comment added by 169.233.41.37 (talk • contribs) 05:53, 19 April 2010
